The £5995 Leema Acoustics Libra is both a DAC and a preamplifier with a plethora of inputs that should be ample for anyone. Dominic Marsh gets to grips with it for Hifi Pig. More »
The Formula DAC is the first in the aqua – acoustic production to show a proprietary D/A conversion system, that they have named Optologic DAC. This conversion system follows the same multibit technology (already used in the previous DACs such as La Voce and La Scala) but with a discrete R2R resistors ladder instead of Burr Brown PCM1704 dacs.
Galvanic and magnetic isolations are implemented between the FPGA and the four branches of the R2R ladder converter. This creates complete isolation of all digital circuitry – including the clock – from the analogue section for a pure clean ground plane. It also plays the main role in the differential management of the R2R ladders, “achieving perfect symmetry between the counter-phase halves”.
The Formula Dac uses no digital filter or any other compensation, relying instead on attention to each sub circuit. The analogue and digital power supplies are executed purely discretely by extensive use of BJT, Mosfet, Jfet and ultra-fast diodes. Passive parts were selected not just for the best sonic result but also for their top quality, longevity and reliability. With the exception of six superior quality electrolytics, all other caps are Tantalum, solid-polymer OS-CON and double-metalized MJP. The signal path itself is direct-coupled and free of all capacitors. The two output stages (one single-ended, one transformer-coupled balanced) use discrete BJT and JFet with metal-film resistors. All the electronics parts show an ultra low RF noise.
Australian brand Burson have announced a Noir Edition of the Conductor V2+ headphone amplifier/DAC/preamplifier. Hifi Pig had one of the older versions of this in house for a few months driving Audeze cans and it offers very good value and great sonics for money at USD 1499.

Schiit Audio have introduced Modi Multibit, the most affordable DAC in the Schiit Multibit lineup. Modi Multibit, which retails for £249, joins Bifrost Multibit, Gungnir Multibit, and Yggdrasil in the Schiit Multibit DAC line.
“Modi Multibit smashes the price barrier in advanced multibit DACs,” said Mike Moffat, Schiit’s Co-Founder and head of digital development. “It is the most affordable multibit DAC built on a modern architecture—from any manufacturer, in any country in the world.”
Modi Multibit is built on Schiit’s proprietary multibit DAC architecture, featuring Schiit’s unique closed-form digital filter on an Analog Devices SHARC DSP processor. For D/A conversion, it uses a medical/military grade, true multibit converter specified down to 1/2LSB linearity, the Analog Devices AD5547CRUZ.
“It may seem incredible that, just a little over a year after we introduced our first multibit DAC, Yggdrasil, we’re introducing a multibit DAC that includes a version of the same digital filter and a real multibit D/A converter for 89% lower cost,” said Mike. “But we don’t believe that you should have to spend a boatload for great sound, so it makes complete sense.”
Modi Multibit is Schiit Audio’s fourth multibit DAC, and is built on Schiit’s second major multibit platform that was developed from the ground up. It fits into the line as follows:
Yggdrasil: Schiit Multibit 1 Platform, Modular/Upgradable, 8X Closed-Form Filter, AD5791BRUZ x 4, Choke-Input, Shunt Supplies, Discrete JFET Buffer Output, Gen 3 USB, £2045
Gungnir Multibit: Schiit Multibit 1 Platform, Modular/Upgradable, 8X Closed-Form Filter, AD5781BRUZ x 4, Discrete JFET Buffer Output, £1125
Bifrost Multibit: Schiit Multibit 2 Platform, Modular/Upgradable, 4X Closed-Form Filter, AD5547CRUZ, £540
Modi Multibit: Schiit Multibit 2 Platform, 4X Closed-Form Filter, AD5547CRUZ, £249
Multibit DACs differ from the vast majority of DACs in that they use true 16-20 bit D/A converters that can reproduce the exact level of every digital audio sample. Most DACs use inexpensive delta-sigma technology with a bit depth of only 1-5 bits to approximate the level of every digital audio sample, based on the values of the samples that precede and follow it.
MUTEC, German manufacturer of professional and audiophile consumer audio equipment, say they are excited to introduce the firmware V1.10 for their MC-3+ Smart Clock USB. The new firmware V1.10 will not only introduce several functional improvements, it also presents a significant step-up for the already exceptional sound performance of the MC-3+USB say the company. Furthermore, the update will be free to all users and is ready to be installed on their own at home or at the studio.
- Free, user-executable update
- Painstakingly optimized re-clocking algorithm
Improving the already exceptional sound quality to achieve even more clarity, resolution, and presence
- PCM/DSD auto-detection
Enjoy music via USB up to 192 kHz PCM and DSD/DoP streams (up to DSD256 and DoP128 respectively) without the need for manual switching
- Bugfixes and functional improvements
Windows only at the moment, but Mac update coming soon
One of the most significant functional improvements and most requested feature of the firmware V1.10 is the automatic detection of DSD and PCM streams when using the MC-3+USB for audiophile computer audio playback via USB. MUTEC CEO Christian Peters comments: “Convenience is key for our high-end consumer audio customers and having to switch modes depending on the source file when playing back a mixed format playlist for example was a major nuisance.” From now on, the user simply has to select the USB input from the reference menu (all top three LEDs now illuminate) and the MC-3+USB will automatically adapt to PCM streams with up to 192 kHz sampling rate and DSD/DoP (DSD256 and DoP128 respectively).
Christian continues: “Our development engineers have painstakingly tweaked the DDS algorithms under the hood yielding a new level of sound quality. This is an achievement we’re particularly proud of and that all users will benefit from.”.
The firmware release package will contain several update files and a comprehensive guide taking the user through the process step by step. The update will be made available via MUTEC’s website as a zip-archive download. At the moment, the update is limited to Windows users only, but a Mac version of the update is expected to follow soon.
Expect a review of this the MC-3+USB on Hifi Pig soon.

Absolute Sounds say it is pleased to announce its appointment as sole UK distributor of dCS audio equipment with immediate effect.
Based near Cambridge, dCS is a world leader in digital audio replay systems for domestic and professional use. The company is widely acknowledged to have pushed the digital audio performance envelope as a result of its many proprietary technologies, most famously the dCS Ring DAC™ – a shining example of British technological ingenuity.
Originally called Data Conversion Systems, dCS was founded in 1987 to manufacture high-performance Analogue-to-Digital Converters (ADCs) and Digital-to-Analogue Converters (DACs) for major telecommunications companies and military agencies, whose primary requirement was technology that delivered state-of-the-art precision, linearity and reliability. The company’s first project was to develop the Blue Vixen radar system for the Royal Navy Sea Harrier FA2 fighter aircraft.
In the late 1980s, dCS began making ADCs and DACs for music reproduction – first for the rapidly growing digital recording industry, then for use in the home. While the company’s focus had changed, its commitment to producing digital conversion systems of unrivalled accuracy had not, the company’s R&D-led approach further growing its reputation for leading-edge innovation.
dCS is responsible for many ‘firsts’ throughout its timeline, including the world’s first 24-bit audio DAC and the first-ever 24-bit/96kHz analogue-to-digital and digital-to-analogue conversion systems. No company has played a more pioneering role in the development of today’s hi-res digital music scene than dCS, and its products continue to enjoy an exceptional reputation among industry professionals and discerning music lovers around the world.
Today, dCS has three main product lines – Debussy, Rossini and Vivaldi – each designed from the ground up to represent the pinnacle of digital audio performance. The company’s DAC technologies are truly unique, utilising proprietary hardware and software in place of ubiquitous, off-the-shelf chip solutions. A modular design approach delivers a clear upgrade path, allowing dCS owners to update their state-of-the-art digital playback systems as technology progresses, and all the company’s products are hand-built in the UK.
Commenting on the appointment of Absolute Sounds, David Steven, Managing Director of dCS, said:
“dCS has been developing state-of-the-art digital audio technology for almost 30 years. Since becoming Managing Director in 2009, I have been committed to furthering our pioneering tradition with products that deliver the finest performance available today.
“One of the most crucial elements in helping our customers enjoy an unrivalled listening experience is the support offered by our global distributor and dealer network. We are constantly looking for partners who share our passion and commitment to deliver an unforgettable in-home musical experience.
“Absolute Sounds has been the primary architect of the UK’s high-end audio scene over the past four decades. We share a passion for providing wonderful sound and exceptional customer service to discerning music lovers; by working together we can make that experience even stronger.”
Ricardo Franassovici, founder and Managing Director of Absolute Sounds, added:
“There are very few digital audio products in the world that deliver the level of performance we demand from the brands we represent. The components made by dCS unquestionably do, with the company’s proprietary technologies cementing its status as a true digital audio pioneer.
“When we auditioned the latest dCS Vivaldi 2.0 digital playback system, we were inspired by its magnificent sound quality. And when David Steven and his team of engineers shared their forward-thinking vision with us, we became excited at the prospect of our new partnership. On a personal note, having known David’s father prior to his death in 2009, I am delighted at the prospect of working with the innovative company that he helmed for many years and that his son now steers toward further success.”
Having heard a full dCS digital front end we at Hifi Pig can attest to how good their kit actually is!
Burson got in touch with Hifi Pig to tell us they are introducing the pocket sized, USB powered “Conductor Air”. Details are pretty scant at the moment but they say that just like its full sized sibling, its a USB DAC, Head amp, Preamp 3 in 1 unit.
- 185g uni-body aluminium enclosure
- Xmos USB receiver capable of native streaming DSD256, DXD, 32bit/384khz audio files
- SABRE32/ESS9018 DAC chip, just like the desktop Conductor V2+
- Raising a 5V USB power to 18V resulting in 4 times the dynamic range and 500mW into 32ohm of power
- Remote controlled preamp.
The conductor Air will come in both silver and black and will cost $499 when it is available in late August.
Audiolab’s M-ONE compact integrated amplifier is the latest addition to the M-DAC family, harnessing the company’s acclaimed DAC and amp tech in a single diminutive box. The M-ONE takes Audiolab’s DAC technology, adds high performance pre/power amp circuitry and a range of connectivity options including aptX Bluetooth.
Outwardly, the M-ONE is almost identical tothe M-DAC+, Audiolab’s flagship DAC component. It sports the same compact aluminium case, small enough to sit unobtrusively on a desk, table or shelf, with the same central OLED display and dual rotary control scheme. But while standalone DACs like the M-DAC+ require a separate power amp to drive a pair of speakers, the M-ONE has stereo power amplification plus preamp facilities for analogue sources as well as digital. The M-ONE shares the same core D/A conversion technology, based around the peerless ES9018 Sabre32 Reference chip family from ESS Technology in this case, the recently introduced two channel ES9018 K2M, little brother to the flagship eight channel ES9018 chip found in the M-DAC+. It sports the same patented 32-bit HyperStream® DAC architecture and Time Domain Jitter Eliminator, unique to the Sabre32 Reference family, surrounded by Audiolab’s signature circuitry. The preamp section mixes minimalist design with high-quality components, ensuring a short, direct signal path to maintain sonic purity. Volume is digitally controlled in the analogue domain, outputting directly to the Class AB power amplifier, which delivers an output of 40W per channel into 8 ohms–plenty of power to drivee fficient modern speakers.A low-noise linear power supply benefits all circuits from the DAC to the power amp, incorporating a shielded, precision-wound toroidal transformer and multiple power supply sections to keep crossover interference to a minimum. In addition to themain power amp stage,the M-ONEshares the same high-quality headphone amp featured in the M-DAC and M-DAC+, ensuring it’s just as capable with headphones as it is when powering speakers. There are two USB inputs – aType B socket (ideal for PC/Mac connectivity) andaType A socket (useful for Apple iOS device docking and playback). Both USB inputs are compatible with PCM data up to32-bit/384kHz, as well as DSD64/128/256, and both are asynchronous–data is regulated by the precision master clock in the M-ONE’s DAC section, rather than by the source device, thus helping to minimise jitter. Other digital devices can be connected via optical or coaxial cables; one input of each type is supplied, supporting PCM data up to 32-bit/192kHz.These are accompanied by two RCA-phono inputs for analogue source components, while those who enjoy the freedom of wireless connectivity can pair smartphones, tablets and computers via Bluetooth, with support for the sonically superior aptX codec.
The Audiolab M-ONE is available from August in finely textured black or silver. RRP is £799.95

UK based Veracity Audio’s Mystra is a dual mono design with dual DAC architecture. The dedicated 24bit dual mono, multi-bit conversion handles PCM files without sample rate change and the stand-alone ∆Σ DAC/reconstruction filter offers playback of DSD64 and DSD128 natively without digital processing. The DAC features auto-switching with incoming signal file format, directing DSD to the DSD reconstruction filter and PCM to the parallel PCM only DAC. Both engines share only the SE triode valve analogue stage on a ‘one-at-a-time’ basis.
To match the output of the DAC to any pre or integrated amplifier the DAC is equipped with an analogue volume control designed with non-inductive resistors controlled by relays, with only two resistors in the signal path at any level and R2R shunt operation. For digital-only systems, this volume control can facilitate direct connection to power amplifiers. Volume control and input selector operation can be remote controlled with the custom, handmade handset.
A jitter rejection system for SPDIF inputs is employed with a quad differential receiver for use with a CD transport and any other compatible signal source.
Line preamplifier function is offered for external analogue source to directly use the DACs triode valve stage as an active preamplifier with R2R volume control. Analogue input is via a pair of RCAs whilst output is via RCA and XLR.
Mystra features a Headphone output for 32Ω – 300Ω headphones.
The valve analogue output stage operates in pure Class A. It is a single ended triode design without negative feedback.
Low impedance, high current drive audio outputs are connected directly from the valves through Jensen Copper foil audio capacitors to a stereo pair of RCA single-ended and a pair of XLR passively balanced analogue outputs. Both output types are coherent with any amplifier input with RCA`s 209Ω and XLR`s 600Ω output impedance.
The valve stage consists of a pair of 6SN7 signal drivers, a pair of ECC82 output drivers and a pair of CV574 full-wave valve rectifiers.
Veracity Audio has separated out the digital and analogue power supplies and also the left and right channels. Strictly linear, ultra low noise power supplies were designed, each for the specific application including internal power supply for the USB interface. All power supplies are capable of high current delivery and feature separate power rails with dedicated decoupling for each individual power consumer. Multiple choke filters system and ultra low impedance film and organic polymer capacitors are used to provide the purest power flow possible. The DAC also features a built-in, selected Schurter mains filter.
Mystra DAC is equipped with Soft start, giving the time for the valves to warm-up. During this warm-up time signal outputs are muted with the Audio comes-on automatically after 70 seconds.
The long-awaited DAC/valve headphone amp and preamp from the Danish brand Copland has arrived in the UK courtesy of Absolute Sounds.
The heart of the DA215 is a D/A converter with multiple S/PDIF inputs, PCM, and DSD capabilities using the ES9018 Reference 32-bit DAC in quad-mono configuration, 8 mono to 2 stereo configuration. The company’s press release has the following to say “Combining four in-phase and four opposite-phase converters per channel, the statistical properties of the signals are taken to advantage; the signal power of the phases correlate and add-up in constructive addition, whereas the noise power of the phases are de-correlated, improving the signal to noise ratio of the resulting analogue waveform”.
The class-A buffering technology of the analogue filtering sections is borrowed from the Copland CD-players and composed by discrete transistors.
The DA215 incorporates an asynchronous USB input, three S/PDIF digital inputs, an analogue input, two analogue outputs (fixed and variable) and a complete pre-amplifier with analogue volume control and front panel headphone output featuring vacuum tube gain stages.
You can use the DAC215 for headphones playback. However, you can also use it as a high-end pre-amplifier with volume control, using the amplifier RCA outputs. The volume control and pre-amplifier functionality can be bypassed for pure DAC mode.
The DA215 USB features USB 2.0 PCM 24/32 bit data transfer to 384 kHz, including native DSD64 and high resolution DSD128. The input is converted to i2s and it is connected directly to the DAC chip. Once connected, the computer recognizes the DAC and routes the digital audio data to it, bypassing the source device’s internal audio circuitry. The asynchronous USB-B port connects to the computer’s USB-A port. No power is taken from the computer. The regulated power supply for the USB input section has its own winding of the power transformer and the noisy computer line is completely interrupted by the use of digital Isolators.

Cyrus Audio is launching its first Kickstarter campaign on 1st July, with the aim of raising £50,000 to develop the SoundKey, a micro-sized DAC designed to get the best musical performance out of mobile phones.
Aimed firmly at music lovers who use their mobile phones as the primary source, the SoundKey bypasses the low quality internal circuits of the phone and takes the digital music signal directly to its own DACs and amps. With just 50mA current draw from the phone it won’t run the batteries down too quickly.
Simon Freethy, managing director of Cyrus, says, “There’s a whole new generation of music lovers who just don’t know how good the music on their phones can sound, as it’s let down by the low quality DACs and amplifiers employed in the phone. The Cyrus engineers, using their 30 years experience building products that provide a better music experience, have come up with a world-beating solution in the diminutive SoundKey.” He continues, “It will significantly enhance the enjoyment of content from phones and we are so excited by it that we want to invite consumers to be part of this revolution. Join us at our dedicated SoundKey microsite and register your interest to be one of the first backers and among the first to own one of these really cool products.”
Kickstarter pledge levels will be announced shortly and Early Bird and VIP packages will be available that reward the first people who get behind the product.
Chief Technical Officer at Meridian, Richard Hollinshead comments: “The Meridian Ultra Digital to Analogue Converter is the culmination of nearly two decades of research and engineering. With considerable connectivity options, user features, and format support, the Meridian Ultra DAC incorporates an extensive list of performance-enhancing technologies, including Dual Mono DAC cards, DSP filter options, upsampling, and apodizing. This dedicated DAC utilises Meridian’s renowned audio expertise to set a new standard in the analogue realm”.
Connectivity options include USB 2.0, S/PDIF, TosLink, 75 ohm BNC, and AES3 on XLR, as well as Meridian’s Speakerlink and the Sooloos music-management platform. One pair of balanced and one pair of unbalanced analogue outputs are also provided.
The Meridian Ultra is a 384kHz/24-bit dedicated DAC capable of playing virtually any recording format including DXD, DSD64 and DSD128 (DoP), and MQA.
Significant user features are provided, including LipSync, PC setup, and RS232 enabling integration with third-party systems such as Control4 or Crestron. The Ultra DAC is the first Meridian product to give users the option to select one of 3 upsampling filters when reproducing sources with a sample rate of 44kHz or 48kHz, such as CD or DAT. In addition, a dedicated clock card is included for the lowest possible jitter.
The Ultra DAC is the first product in the world to include MQA Limited’s Hierarchical Converter Technology, which employs multiple converters to increase temporal resolution while reducing noise and quantization errors.
Another first for a Meridian product is the construction of the Ultra’s Dual Mono DAC card, which incorporates multiple regulated power supplies and eight-layer circuit boards with low- impedance ground-planes, for isolation and the low-noise grounding. A fully linear power supply provides isolation from the AC supply, and DC-coupled output prevents degradation from AC coupling capacitors. Even the Ultra DAC’s front panel was designed for quiet operation, with non-ferrous construction, and a static LCD display chosen for its low electrical noise and ease of readability.
The Meridian Ultra DAC is built by hand in the UK and is available in beautiful high gloss black as standard. Other colour options are available using Meridian’s Select bespoke colour service (£500).

The High End Show at Munich is an absolutely gargantuan task for anyone to undertake but it always ends up been worth the effort of trying to see absolutely ever room you can as you come across some real gems that you just weren’t expecting…and of course some that you perhaps expected would be great anyway.
The vast majority of exhibitors go to an extraordinary amount of effort to make their rooms the very best they can be and all credit must go to them. As always though there are the rooms and stands that really leap out at you and remain in your memory for the whole of the show and a long time afterwards.
So, here are some of what I considered to be the real gems of this years show. They’re in no particular order and are likely to be in the order we happened across them. More »

Mytek Digital has announced the release of the MQA™ firmware update which enables the new Brooklyn DAC/ Headphone/Phono Preamplifier to decode all MQA files — in addition to all other formats, including PCM 384k/32bit and DSD256. After Meridian, Mytek is the second MQA licensee to release the firmware update with the MQA technology.
MQA is an end-to-end technology that captures and delivers master quality audio in a file that’s small enough to stream or download. And because it’s fully authenticated, the listener can be sure they are hearing exactly what the artist recorded and approved in the studio.
Later this year, availability of high-resolution music streaming services using MQA format is expected.
In a move that is rather unusual in a $2,000 DAC, Mytek has engineered the very Brooklyn DAC to also include a Phono Preamplifier and Headphone Amplifier.

Auralic North America Inc. and its parent company, Auralic Limited, is introducing the new Altair Streaming DAC. The company say that the Altair can act as an easy-to-use Home Music Center with more than 15 input sources including: Streaming Inputs: Network Shared Folder (NAS), USB drive, Internal music storage (optional), uPnP/DLNA media server, TIDAL and Qobuz streaming, Internet Radio, AirPlay, Bluetooth, Songcast and RoonReady; Digital Inputs: AES/EBU, Coaxial, Toslink, USB device to computer, 2 USB host for storage and DAC, RJ45 Gigabit Ethernet and 802.11b/g/n/ac Tri-Band WiFi.
Xuanqian Wang, Auralic’s president & CEO, said: “The new ALTAIR is both a high quality streamer and DAC, and was designed based on feedback from dealers for an exceptional yet convenient-to-operate digital Source unit at an $1,800 – $2,000 price point.
“Some may consider this as a combination of Vega and Aries or the upgrade version of Aries Mini with digital input. However, the Altair is definitely a Line Extension, and not replacing the Aries Mini, or Auralic’s award-winning Vega DAC or Aries Streamers which represent the very highest level of sound quality.”
The Altair streaming DAC utilizes Auralic’s Lightning technology. Launched in 2014, Lightning was the audio industry’s first streaming technology that supports DXD and Quad-Rate DSD playback through a WiFi network. It also offers features such as Gapless Playback, On-Device Playlist and Multiple-Room functions, as part of Auralic’s ongoing program of offering regular upgrades that download in the background. Memory Playback, the latest feature added to to the Lightning streaming technology, allows the Altair to fetch and cache the entire track in its memory or system storage in advance to improve the sound quality, and also play locally without the need of network data transfer. Using Lightning DS, you can also stream TIDAL, Qobuz and listen to Internet Radio at any time. Altair’s AirPlay, Songcast and Bluetooth functions provide alternative ways to stream your favorite music from Apple Music, Spotify and other service providers through your smartphone or computer.
Altair’s’s streaming function, operated by Auralic’s Lightning DS control App, is available on iOS platforms right now, with Mac and Windows versions in development. It is also compatible with other 3rd party OpenHome or UPnP control software for playback. Altair also works as a RoonReady endpoint to use with Roon software, bringing you a new way to discover and listen to music. The unit’s other inputs include AES/EBU, Coaxial and Toslink, and a USB connection to a computer working as a standalone USB DAC.
When purchasing Altair you can add an optional 2.5-inch HDD or SSD for internal music storage, turning the ALTAIR into a Music Server.
Cosmetically, the new Altair shares the same size enclosure as the Vega DAC, including a 512×64 pixels OLED Display (although the content is different from the Vega). A headphone jack is located on the front panel.
The Altair has a MSRP of $1,899. Shipment will commence in June, following the Munich HIGHEND Show.
Altair is powered by Auralic’s proprietary Tesla hardware platform that includes a Quad-Core Coretex-A9 processor running at 1GHz, 1GB DDR3 onboard memory and 4GB system storage. The Tesla platform has a calculation ability of 25,000 MIPS and can decode including AAC, AIFF, ALAC, APE, DIFF, DSF, FLAC, MP3, OGG, WAV, WV and WMA. Future features planned include DSD Upsampling, Room Acoustic Treatment and MQA support. All these features can be delivered through automatic online updates without user’s attention.
Femto Master Clock
The dual-frequency Femto Master Clock inside the Altair is specially designed and optimized for its ESS Sabre DAC chip: with one frequency for playing music with a sampling rate which is the multiple of 44.1K, and a second for 48K. The Femto Master Clock, which is powered by a 9uV dedicated power supply that has a very low phase noise performance.
Linear Power Supply
Auralic uses Purer-Power™ linear power supply technology on the Altair where AC power firstly goes into a power purification module, and the DC current and noise from both within and outside audio frequencies can be reduced by as much as 90dB. The purified AC power is then fed to a transformer.

It’s been almost four years since the original DragonFly (v1.0) launched and then a year and half later, DragonFly introduced the updated v1.2—for €149.
Now, AudioQuest is to introduce two new DragonFlys that will work with Apple and Android™ phones!
AudioQuest worked alongside Microchip Technology to develop a new high-performance, full-speed USB microcontroller (a DAC’s input processor) that delivers improved signal-to-noise ratio and significantly lower power consumption. Drawing 77% less current than the DragonFly v1.2’s microcontroller, the new Microchip MX microcontroller enables compatibility with Apple and Android smartphones and tablets. For use with Apple iOS devices, Apple’s Lightning-to-USB Camera Adaptor is required; for use with Android devices, a Made for Android (OTG) adaptor, such as our DragonTail USB Adaptor For Android Devices, is required.
The new DragonFly models also incorporate improved 32-bit ESS Sabre DAC chips—the 9010 in Black and the higher-performance 9016 in Red—both of which employ minimum-phase filtering. While DragonFly Black uses the same high-quality headphone amp and analogue volume control found in the DragonFly 1.2, DragonFly Red includes the latest ESS headphone amp and a bit-perfect digital volume control that resides on the 9016 DAC chip itself.
DragonFly Black outputs 1.2 volts—enough power to capably drive all preamplifier input circuits and all reasonably efficient headphones. Meanwhile, with its higher 2.1-volt output, DragonFly Red is compatible with an even wider range of headphones, including power-hungry, low-efficiency models. For reference, DragonFly 1.0 and 1.2 featured 1.8-volt output.
The difference in maximum output between DF Black and DF Red is essentially irrelevant with our NightHawk headphones, as they can be easily driven by either model, but Red’s higher output is an important advantage with some of the more inefficient headphones on the market. However, the difference in sound quality between the two new models is always meaningful, and is important whether feeding headphones or the Aux input of an audio system. At the same volume, Red has much more “torque,” “grip,” and “muscle” than Black. Red simply sounds cleaner and clearer overall, enabling a larger soundstage with each instrument or voice more nearly in its own space.
And, more good news: The new DragonFlys are software upgradeable through complimentary Windows and OS X desktop applications. As new developments arise in music player applications, streaming protocols, or other associated software, DragonFly users will be able to incorporate those updates into their existing devices.
DragonFly Black for only €99, with better sound than any previous DragonFly for less money than any previous DragonFly, and DragonFly Red with much better sound at only €199—and both compatible with phones—how much good news can you stand?!

Romanian manufacturer Rockna have announced the new Wavedream DAC series will be available in the UK soon. There are 2 main models : Edition (featuring Rockna RD-1 discrete DAC modules) and Signature (featuring Rockna RD-0 discrete DAC modules) with each version being available in single ended or balanced configuration.
In addition to the Femtovox clock system, both Edition and Signature benefit from a new discrete output stage, have an improved power supply section and in addition have dedicated sections for digital and analogue areas. There are 3 separate transformers, and all power supplies are low noise linear – no switchmode power supplies are used whatsoever. There are a total of 20 linear regulators inside the DAC.
The RD-1 module has a 26-bit ladder structure, while RD-0 is a 27 bit ladder structure. Both are FPGA-based, meaning they have their own (upgradable) firmware. A custom solution, freed from the limitation of the available chipsets, comes into place, allowing them to design and build from the scratch an entire digital audio system.
All building blocks of the Wavedream DAC concerning digital processing are built entirely on a single piece of programmable silicon – an FPGA . With an FPGA, the internal hardware architecture could be described by a piece of software. When upgrading the Wavedream with new firmware, you actually changing its hardware. This system allows flexibility, obsolescence protection and lets Rockna improve the sound of your DAC by changing its internal architecture, or to add new features, or improve the existing ones.
The Wavedream upsamples any material with a fixed rate of 16x. The DAC modules will decode the digital stream with a rate of 768Khz, or 705.6Khz, respectively, according to input sample rat which the guys at Rockna say is the rate they found to be optimal for analogue performance of the DAC modules. The digital filters are made with the combined effort of 58 DSP blocks, resulting into in 15 GMACS of processing power. The developed filters are unique say Rockna. They avoid standard Nyquist rate filters as Rockna thought they did not “provide the expected performance for the DAC”. After lots of mathematical simulations and careful listening tests, they have created a custom Parks-McClellan upsampling filter. There are three variations available on current firmware: linear, minimum and hybrid phase.
Finally, the last stage of the signal path is the analogue output stage. Designed from the scratch to work with converter modules RD-0 & RD-1, the output stage is totally discrete and acts as a high-speed buffer. Made entirely with through-hole components (non-smd), Rockna engineers combined J-Fet & Bipolar Devices into a class A design, with a closed-loop output impedance of under 1 ohm and equivalent input noise as low as 1nV, as a perfect match for the converters overall performance.
Both DACs will be available from BD AUDIO in the UK soon.
Unison Research are expanding on their valve-based hifi electronics to produce their first ever dedicated headphone amplifier. The SH is a single-ended, two-stage full-valve headphone amplifier designed to accommodate both traditional analogue sources and modern computer-based audio.
Unison Research have created SH in order to cater for the growing world of headphone audiophiles. As most readers will be well aware, headphones have become increasingly important in the high-end home listening environment and the SH was developed to offer a high-end valve alternative to the many solid-state headphone amplifiers that are currently available.
The SH began with the same basic aim as the company’s Simply Italy integrated amplifier; to produce a world-class sound from a specialised device, using the best technology available. However, to suit the particular factors associated with headphone listening, the development team also had to ensure that the amplifier was designed with low noise characteristics and low internal impedance.
The result was a fairly simple linear circuit with low negative feedback that produces an output voltage which is capable of driving a wide range of headphones, while keeping distortion low throughout the frequency range. To compensate for the low negative feedback required in the design, attention was paid to ensure optimal linearity and increased attention on managing noise to a minimal level throughout the electrical path. “It’s thanks to this design that the SH is able to deliver a consistent, coherent, rich and identifiably “valve” sound character when in use” says the recent press release from Henley Designs, the UK Distributor.
The input stage uses an ECC83 valve, while the output stage uses one EL84 (both valves operating in triode mode). The benefits to using this specific combination of valves are said to be two-fold. First, the application requires reduced power compared to how the valves are usually employed, resulting in extended life. Second, the EL84 is capable of producing enough power to also drive the specially-selected output transformer with optimal electrical and sound character.
The SH has two headphone outputs that are connected in parallel (each with their own EL84 valve) for easy switching between headphones, or to accommodate multiple listeners. There is also a “Sensitivity” switch, to ensure the widest possible range of headphones can be comfortably driven by the amplifier. When set to “High Sensitivity”, the output voltage from the amplifier is reduced, and at “Low Sensitivity” it is at its maximum. The volume stage is entirely passive.
In addition to a standard un-balanced RCA input for connecting any Line-level source, the SH is also equipped with a USB DAC. The asynchronous USB 2.0 technology is the same as found on the recent Triode 25 amplifier, and supports audio formats up to 384kHz PCM and DSD 128. There’s a patented jitter-elimination circuit and galvanic isolation employed between the power areas of the USB interface and the conversion IC.
Aurender has announced that their latest downloadable software upgrade, System SW 4.5.58 (5.5.58), adds several new features, including: Qobuz high fidelity streaming, and the company’s unique Smart Copy®function that allows direct music uploading, within their Conductor App, to any Aurender Music Streamer/Player’s internal HDD directly from your NAS or external USB drive, without using a PC or Mac.
These new features are backward-compatible with any Aurender Music Streamer/Player. The Smart Copy process includes all metadata and the copying of either folders, individual files or both from a NAS or any attached USB drive into the Aurender. One may select a “target” folder of their choice as the destination for the transferred folders or files. It is a “copy” function, and does not currently allow deletion or name changes; this will come in a future software upgrade.
For those Aurender models with two internal HDDs: When the target HDD is full, Smart Copy will copy to the second HDD automatically.
Also included in the latest software upgrade: W20 supports on-the-fly DSD to PCM conversion up to DSD64. (The recently–introduced N10 Music Server has had DSD to PCM conversion since its introduction, and supports up to DSD128.)
Leema Acoustics’ Elements range has expanded to include a new preamp with a high-quality DAC section, offering a wide range of connectivity for today’s digital devices. The new Elements Pre-Amplifier builds on the Leema Acoustics’ Elements integrated, adding a high-quality balanced output.
The new Elements Pre-Amplifier retains the familiar half-width-chassis form factor of the Elements product range and is built to the same standards as the full-width Leema models. A matching 160-watt bridgeable power amp is also available.
Leema Acoustics’ on-board digital to analogue converter offers a 24-bit/192kHz S/PDIF coaxial input, three 24-bit/192kHz S/PDIF optical inputs and a 24-bit/192kHz asynchronous USB input, enabling a wide range of source components.
Analogue inputs include three unbalanced stereo RCA inputs, a pair of balanced inputs on XLR, plus a 3.5mm input jack on the front panel. The output connections include one pair of balanced XLR outputs and one pair of stereo RCA.
Full LIPS® implementation (Leema’s proprietary communication system) allows for easy system integration with other Leema products and home automation systems, and a remote control is also included. Additionally, an internal headphone amplifier provides a useful personal listening option. Finishes include black and silver.
The Elements Pre-Amplifier is available now priced at £1,395
Burson have announced that they have completed the R&D of our 3rd generation Conductor., which is their reference class headphone amp, USB DAC and preamp, 3 in 1. They say “is a major update from previous Conductor models”. The Conductor V2 headphone amp and pre-amp section are powered by a dedicated 70W transformer. Tuned to operate in pure Class A, it outputs over 8 Watt per channel into 16ohm, making the Conductor V2, claim Burson “one of the most powerful headphone amplifiers in the world, capable of driving any headphone”. On the digital front the Conductor V2 features the flagship ESS Sabre DAC, has completely new supporting circuitry and an independent power transformer. The new USB module features a digital interface from XMOS with their 8 core U6 chip supporting native DSD256 playback and up to 32bit depth.
Burson are yet to set a price for it. Instead, they have put the design on Indiegogo to seek community support. With enough contributions from the community, they are hoping to push the price as low as $999 USD for the analogue version (V2) and $1,499 USD of the fully equipped version (V2+). Burson have told us: “We want it to have a lower price so more audiophiles can own this truly amazing machine.”
With their latest release, Italian valve specialists Unison Research have produced a source device that brings digital technologies together into one enclosure, offering a complete solution for audiophiles who “want to get the best from their digital media”. The Unico CD Due supports Bluetooth streaming and acts as a comprehensive DAC capable of accommodating any high-end music player, while also acting as a stand-alone CD player. You will be able to see and hear the new unit at this weekend’s Bristol show with Henley Designs in Room 422.
The hybrid Unico range from Unison Research combines valves with other solid state devices. The Unico CD Due joins the range as the new flagship source, and shares the same “three-panel” aesthetic of the range-topping Unico 150 amplifier.
The DAC portion of the CD Due is equipped with USB, S/PDIF, AES/EBU and Toslink inputs, which all route through the built-in ESS Sabre ES9018K2M DAC chip. The USB input uses XMOS technology to handle PCM signals up to 384kHz and DSD signals up to 11,2896MHz (DSD256), effectively encompassing almost every audio format and sample-rate currently available. The more “traditional” digital inputs handle 24-bit/192kHz (24/96 via Optical) PCM signals, allowing myriad of high-quality sources to be connected with ease.
The CD Due’s Bluetooth functionality allows for wireless streaming from any Bluetooth-enabled smart device. Set-up is said to be simple. Finally, the CD player section uses a premium mechanism and sleek drawer-loading system. Internally, the CD mechanism is shielded by a thick metal cover, to avoid interference.
“What helps the CD Due stand apart from its competitors is not just its feature set, but its rich, enveloping sound; which owes much of its expression to the valve output stage” says the company’s press release. The four ECC83 valves are configured in an innovative totem-pole arrangement with balanced input. This particular layout allows for a high immunity to power supply noise and brings together a “triode” sound with “the drive capability of a cathode follower stage”. The rest of the board also utilises premium components and shorter signal paths. For even more durability you can also use the CD Due as a transport only, utilising the three digital outputs on the back panel to run with another external DAC.
The CD Due is purpose-designed to separate the digital and the analogue portions of the circuitry and the DAC portion has carefully-managed filtered power distribution. The DAC chip boasts a “jitter eliminator” design with a signal-to-noise ratio of 128dB and distortion of 0.0003%. The clock system uses a quartz oscillator with high precision and low phase-noise.
The Unico CD Due makes controlling all its features easy, via the supplied RC2 system remote and its 128×64 OLED screen. With three switchable filters and even the option to bypass the valves with a “solid-state” output buffer – the CD Due can suit any high-end system or sound preference.
The Unison Research Unico CD Due is available in the UK now in Silver finish.
The Unico CD Due can be special ordered in Black for an additional £100.00 (SRP).

Roksan Audio’s K3 range of hifi electronics has been a resounding success since its introduction in 2014. Consisting of a high-specification integrated amplifier, CD player and a new CD/DAC; Roksan are now introducing their much anticipated stand-alone Digital-Analogue Converter (DAC).
The K3 DAC was first teased at Munich High End in 2014, and since that point extensive development has forged it into a “superb sounding audiophile device” that meets the highest specification possible, while maintaining a user-friendly interface. In that way it perfectly matches the K3 Series’ mantra: Style. Performance. Function.
At its heart is a DSD1794A DAC chip from Texas Instruments. This chip handles both PCM (up to 24-bit / 192kHz) and DSD (up to DSD 128) data streams utilising the advanced DAC architecture to secure excellent dynamic performance and improved tolerance to clock jitter. This allows for a consistent high performance across the myriad of input options at your disposal, including 1 x AES3/SPDIF (XLR), 1 x Optical, 1 x Coaxial RCA and 2 x USB (Type B).
The K3 DAC is also the first product to use Roksan Audio’s new wireless technology, K-LINK. K-LINK allows for uninterrupted CD-quality wireless streaming from a digital or analogue transmitter at up to 150m range (150m range is only when the dongle and receiver are in a clear line-of-sight. In a typical household, 30m+ is a more expected range).
The K3 DAC is supplied with a digital USB dongle for wireless streaming from a Laptop or computer with support for Mac and Windows, while the optional analogue transmitter allows for wireless streaming from a traditional Line-level hifi source. The analogue transmitter is available separately for £125.00.
The K3 DAC is available in the same three finishes as other K3 Series products; Anthracite, Charcoal and Opium. Control over inputs can be achieved via the front panel or through the supplied R7 System Remote, which also works with the K3 CD players and K3 Integrated Amplifier.
The K3 DAC is available in the UK now.
Chord Electronics, has joined forces with award-winning hifi, home cinema and TV retail giant Richer Sounds, to make its Mojo DAC/headphone amplifier more accessible than ever before.
Richer Sounds, winner of Which?

Computer Audio Design’s USB digital-to-analogue convertor (DAC) has been upgraded. Computer Audio Design has announced a refit to its CAD 1543 DAC, now using proprietary EMI/RFI reduction materials, improved DAC circuit boards, single-crystal UP-OCC internal wiring and refined power supply filtering, to create the CAD 1543 MKII DAC.
CAD is one of a handful of digital audio companies offering resistor-ladder DAC technology, along with no oversampling and no filtering, which CAD believes offers a distinctively different sound than most digital audio products on the market today – a sound that is tangibly closer to the original performance they say.
The CAD 1543 MKII DAC takes its name from the application of an increasingly rare resistor-ladder convertor chip, the Philips TDA1543/N2, with its selected 16 devices now mounted on a revised four-layer circuit board. This new layout minimises intrinsic noise, optimising the chips’ specifications to now allow native conversion of 192 kHz PCM audio.
And where most conventional modern D-A convertors employ over-sampling techniques and a digital interpolation filter, the CAD DAC unashamedly adopts the non-oversampling (NOS) approach in order to protect precious timing resolution. With no filter to ring and smear the fundamental timing of impulsive data – the shape of natural music – the 1543 MKII brings to life both the subtle and macro dynamics of recorded sound.
The hyper-minimalist design is engineered with the fewest number of switches and connectors between mains plug and output sockets. It features a single USB 2.0 input that galvanically isolates the 16 TDA1543 chips from a connected PC. The analogue output sees a single pair of low-mass pure copper RCA phono sockets wired directly to the chips through a passive I/V stage. The summed output of paralleled multi-bit convertor chips means there is no need for additional signal amplification or buffering, thereby removing unnecessary signal stages.
Signal wiring has been updated to single-crystal OCC (Ohno Continuous Casting) copper, custom manufactured to CAD specifications. The casework retains its laser-cut 10 mm-thick acrylic construction – available in black as standard or other colours to special order– and is now supplemented with internal RFI/EMI materials to reduce the effects of high-frequency interference on the circuit boards and their ground planes.
Further fighting the insidious effects of EMI/RFI, Computer Audio Design has redesigned the power conditioning at the unit’s power input, helping minimize AC line noise from the DAC; as well as isolate neighbouring audio components from any residual digital noise released by the DAC.
The overall result of such scrupulous attention to power supplies and potential noise sources is an audio convertor that seems to paint ink-black quietness behind the sound. A DAC that preserves and projects the rhythm and drive of dynamic music.
Computer Audio Design 1543 MKII DAC key features:
Five independent transformers feeding five fully discrete linear voltage regulators for the cleanest power to each modular section of the unit.
Custom 10 mm acrylic case selected for superior acoustic properties.
NEW: additional internal EMI/RFI materials to lower electromagnetic interference noise floor.
NEW: redesigned mains power conditioning to reduce ingress and egress of mains-borne noise.
Sixteen Philips TDA1543/N2 resistor-ladder chips.
Filterless NOS design for unparalleled time-domain replay accuracy.
NEW: custom four-layer PCB to support DAC chips.
Passive output stage with Duelund Coherent Audio capacitors and selected US-made audio resistors all made to CAD specifications.
NEW: internal signal wiring upgraded to custom UP-OCC copper.
The 1543 MKII DAC is made in a modular fashion to make future upgrades possible ensuring your investment will last a lifetime.
The CAD 1543 MKII DAC is available now, priced at £7,250 (incl. VAT).
Owners of the original 1543 DAC can opt to have their units refitted to full MKII specification at a cost of just £600.
A full size integrated amplifier with phonostage, plus a CD player that is also a streamer for just shy of £1200 seems like a good deal. Stuart Smith investigates. More »
Audiolab launches the premium version of the M-DAC this month. The new M-DAC+ will sell alongside the classic M-DAC, sporting a number of enhancements both inside and out in return for an additional £200.
Like the M-DAC, the new M-DAC+ is a high-performance, multipurpose audio DAC (Digital-to-Analogue Converter) for home use, designed to sit on a desk or table, or integrate into a hi-fi system. It incorporates an audiophile-quality digital preamp and Class A output stage for connection to a power amp and speakers (the output can be fixed for use with an existing preamp or integrated amp). A high-quality headphone output is also provided.
The new M-DAC+ is based firmly on the classic M-DAC, with carefully targeted improvements in key areas – a logical move, given the original model’s sustained popularity over the last four years. Like the M-DAC, the M-DAC+ is built around the ESS Sabre32 9018, a 32-bit DAC chipset. There’s a proprietary, discrete master clock to minimise jitter, coupled with extensive time domain isolation and there’s a A JFET Class A output stage.
Compared to the classic M-DAC, the most immediately obvious change is to the aluminium case and control scheme. The M-DAC+ features a new chassis, with the OLED display window now centrally positioned and rounded at the sides, in keeping with Audiolab’s recently launched 8300 Series components. The display is flanked by two rotary controls, one to adjust volume and the other to select settings, replacing the buttons found on the classic M-DAC.
Under the hood lie a number of performance-related enhancements. The M-DAC+ now processes audio data up to 32-bit/384kHz via USB; this is a far higher specification than that required by current hi-res music formats, ensuring this new addition to the M-DAC family is fully equipped for future advances in ultra-high-definition digital sound.
The USB input now also supports DSD files (the digital audio system originally developed for Super Audio CD), offering compatibility with DSD64, DSD128 and DSD256. This is a significant addition, as DSD has an important role to play in the developing high-resolution downloading and streaming scene.
Like the classic M-DAC, the M-DAC+ features user-selectable filters for optimal listening and measurement modes, in addition to more conventional types for easy comparison.
These filter settings allow the user to tune performance to suit his or her preference, depending on system configuration, digital file quality and musical taste. The M-DAC+ inherits seven filter settings from the M-DAC for PCM files and adds four more for DSD playback, allowing the user to optimise the noise floor to suit the performance of the source file and the bandwidth of associated equipment such as amps and speakers.
Another important change relates to the power supply, which has been upgraded and is now fully incorporated within the M-DAC+’s chassis (hence its slightly taller and deeper case compared to the classic M-DAC). A precision-wound toroidal transformer uses multiple windings to feed separate analogue and digital rectification stages. From there, multiple power supply sections feed the necessary voltages to each area of the DAC, keeping any crossover interference to a minimum.
Around the back, digital input options have been expanded with an AES/EBU socket and an additional USB Type A input – ideal for connecting Apple devices – alongside the existing USB Type B connection. These join a full complement of inputs/outputs retained from the classic M-DAC: 2x coaxial digital inputs; 2x optical digital inputs; 1x coaxial digital output; 1x optical digital output; single-ended RCA and balanced XLR analogue outputs; 12V trigger loop.
The Audiolab M-DAC+ comes with a redesigned remote control and is available in black or silver from late-January 2016, at an RRP of £799.95. The classic M-DAC continues at £599.95.
At €11000 plus taxes as tested the Lampizator Big 7 is certainly no budget DAC, but does it deliver on sonic ability? Stuart Smith finds out.
“OK, it would be easy to sum up the sound when listening to DSD files as nothing short of an absolute aural revelation that simply took my breath away with each album I listened to. The immediacy and realness of what was coming out of the speakers was, in my experience, simply without match”
