Aesthetically, the HA-2SE continues the HA-2’s design – genuine leather casing with contrast stitching and bevelled aluminium edges. Inside, the digital-to-analogue converter (DAC) chip is upgraded to the ES9028Q2M, the top-of-the-line from ESS Technology’s SABRE32 Reference series for portable designs. The headphone amplifier is further optimized for very sensitive In-Ear Monitors, with a lower noise floor and higher signal-to-noise ratio over the HA-2.
Featuring hybrid class AB amplification and a USB DAC, the HA-2SE offers high performance digital-to-analogue conversion for Apple’s iPhone/iPod products, a wide range of Android devices, PC and Mac computers. Equipped with a 3000mAh internal battery and OPPO’s patented safe rapid charging technology, the HA-2SE may be conveniently used to charge mobile devices on-the-go and can itself be efficiently charged in 30 minutes.
Being a “Made for iPhone” certified device and coming with a Lightning cable included, the HA-2SE can charge the iPhone and play music at the same time. When used with the right apps, the HA-2SE supports bit-perfect playback of high resolution music, exceeding the 48 kHz sample rate limitation of using the phone’s built-in headphone output or headphone adapter.
In addition to the USB DAC inputs, the HA-2SE provides a 3.5 mm line-in jack for portable music players that do not have a USB-compatible digital output. The same jack doubles as line-out when the HA-2SE is used as a DAC. The headphone amplifier has two gain level settings. The High Gain mode is capable of driving large power-hungry headphones, delivering up to 300 mW into 16-Ohm headphones. The Low Gain mode is intended for sensitive In-Ear Monitor type earphones. For users who like a bit more punch and impact with their music, the HA-2SE offers a Bass Boost function that is implemented purely with analog audio circuits.
Priced at $299, the HA-2SE can be ordered from OPPO Digital’s web site or resellers. The HA-2SE will be available for audition and demo at the Rocky Mountain Audio Fest in Denver during the weekend of October 7 – 9.
Merging Technologies will display a pre-production version of the Merging+NADAC Player at the Rocky Mountain Audio Fest. The result of a dynamic partnership with Roon Labs, On a Higher Note, Merging’s US distributor will be demonstrating the product in Long Peaks on the Mezzanine floor of the Denver Marriott Tech Center. The concept of Roon’s ground breaking player program being offered in integrated solutions is not new; there being many existing partners with products available, but this will be the first time that the focus will shift to a complete turnkey and networked solution offering stereo as well as multichannel capability up to DSD256 and DXD.
The Merging+NADAC player was shown as a concept at the 2016 HIGH END Munich event and was welcomed by the attendees. The ‘single box’ solution with the software and the server combined with a DAC removes the need to have a computer in the living room. The ease with which the whole system can be controlled by your favorite tablet or smart phone enhances the user experience significantly. Integration details such as direct control of the NADAC volume and mute from the Roon user interface, also adds to the overall ergonomics by simplifying the control of the entire system from one single page on one single tablet. The NADAC Player requires only to be connected to the home network to access the remote control tablet through Wifi and stream from NAS servers storing music. When connected on the network any computer can still also stream music to NADAC using Merging Ravenna/AES67 drivers for Windows or Mac, while the NADAC Player enjoys a brand new Merging Linux/ALSA driver. Optional USB drives containing music may be connected directly on the back plate of the NADAC Player.
Merging also announced that this solution can be retrofitted to all Merging NADAC units already in the field and to any units shipping from now on, meaning that early adopters can take advantage of the upgrade if they wish. The Merging+NADAC Player is planned to be shipping in time for CES in January. Prices will show a small increase from the existing DAC despite the huge increase in functionality and convenience.
Roon’s CEO, Enno Vandermeer commented; “We are sure that this combination of the very best audio reproduction and the ultimate user experience, is going to bring back the enjoyment of listening to music in the home.” On Merging’s behalf, Head of Software Engineering and NADAC Product Manager, Dominique Brulhart stated; “The feedback we have had from customers, dealers and distributors over the past few months has convinced us that the market wants an elegant solution in a neater package. The Merging+NADAC Roon player is just that.”
“Katalyst takes an unprecedented level of control over the critical elements that lie at the heart of the analogue signal’s creation, to deliver the most accurate reproduction ever from a digital source” claims the Scottish brands recent press release.
In 2007 Linn launched their original DS player and in 2016, the five key aspects below have been improved utilising Linn’s investments in R&D:
Reference Level – Now completely isolated from noise to produce a high-stability input Reference Level that generates the signal’s amplitude without variation.
Independent Power Supplies – Independent, isolated power supplies are tailored for each process, so feedback from one process cannot influence the performance of another.
Data Optimisation – Linn-designed data optimisation stage that prepares the digital signal for conversion with greater accuracy, minimising errors right at the start of the process.
Master Clock – A single high precision clock with its own independent power supply ensures greater timing accuracy throughout.
Output Driver – The new ultra-low distortion analogue output driver prepares the analogue signal for transmission out of the device, making it less susceptible to noise and degradation.
Every aspect of the original DS design was carefully drawn from first principles in order to optimise performance, from the electronics inside to the clamshell enclosure, machined from a solid billet of aluminium.

Rockna DAC is available from £3950 for the single ended ‘edition’ model with balanced and ‘Signature’ versions also available. Released today is the latest firmware for existing customers and naturally new units will ship with Firmware 4.01 enabling DSD512 compatibility.
The company’s press release says “We always thought that high-end audio should be everything about innovation. Playing around with off-the-shelf available chips is fun and certainly a good and economic way to produce good sound. But once you want to design a cutting-edge product, the off-the-shelf approach doesn’t apply. Naturally, a custom solution, freed from the limitation of the available chipsets, come into place, allowing us 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 – a FPGA . With a FPGA, it’s internal hardware architecture could be described by a piece of software (actually, a very complex one). When upgrading the Wavedream with new firmware, you actually change it’s hardware. This system allows great flexibility, obsolescence protection and let us improve the sound of your dac by changing it’s internal architecture, or add new cool features, or improve the existing ones.”
Release notes for 4.01:
– enabled DSD256 (you need to set ASIO driver as output)
– enabled DSD512 (same)
– enabled dither option (not active in previous version)
– enabled clock option (same)
– brand new upsampling filters
For DSD256/512 playback files are scarce, one way of get great sound is to upsample everything is real-time using HQplayer (which can upsample to DSD512).
Dither “on” will reduce distortion for low level signals (starting at -80 dB and below) ; We used a triangular distribution, shaped mode dither – without increasing noise floor in the audio band.
Clock option works like this : stream mode will track the input frequency constantly while local mode will adjust the lock only from time to time, using a few stages of memory buffers.

Specialist UK Distributor Sound Design Distribution Ltd has signed a UK distribution deal with Mola-Mola. Mola-Mola is the brainchild of Bruno Putzeys, “he wunderkind of Class-D technology” originator of Universal class-D (UcD) in 2001 while at Phillips and as chief tech guru at Hypex, responsible for the development of its game-changing NCore Class-D amplifier technology.
Presented in strikingly distinctive rippled all-aluminium enclosures the ‘Makua’ Control Amplifier, complete with modular DAC and phono options, and ‘Kaluga’ Monoblock power amplifiers will be the first Mola-Mola designs to be made available to UK audiophiles through Sound Design Distribution Ltd.
The Makua is a fully balanced gain stage and routing matrix, accommodating optional DAC and phono stage modules and programmable via a dedicated App through USB or Bluetooth to access any combination of channel, processing and routing. Via the phono stage option for instance, vinyl-lovers can connect up to five turntables and program the settings individually for each. All five inputs are switchable between XLR and floating RCA connections, and all can be assigned as either phono or line.
All stages in the Makua employ discrete amplifier modules using a little known topology called “single-ended driven differential”, which prevents noise from propagating all the way through to the outputs (paralleled for bi-amping). The relay-based volume control directly controls the gain of the output stage.
- 5 balanced and 5 unbalanced inputs, all routable through optional processor boards like the phono stage and DAC
- 2 parallel outputs for bi-amping
- 4 programmable trigger outputs
- Distortion at maximum signal level (THD, IMD): negligible – estimated around -150dB
- Bandwidth >200 kHz
- Dimensions: 420mm(W) x 110mm (H) x 345mm (D). Depth includes volume knob and connectors
- Weight: 11kg
Based on Bruno Putzeys’ Ncore technology the Kaluga amplifier uses a circuit from Mola-Mola derived from the Hypex NC1200 amplifier, featuring an audiophile layout of short, isolated signal paths and eliminating board-to-board connectors in favour of star-quad cables soldered directly to the circuit board. The input stage on a separate circuit board uses the same discrete buffers as those found in the Makua pre-amplifier. The redesigned output filter uses monolithic capacitors.
- Output power: 400 W/8 ohm; 700W/4 ohm; 1200W/2 ohm
- Unweighted Signal/Noise Ratio: 128 dB
- Distortion (THD, IMD): <0.003 % (all frequencies and power levels)
- Bandwidth: >50 kHz
- Balanced and unbalanced input
- 2 pairs of Furutech binding posts, bi-wired directly to the amplifier PCB using Kubala·Sosna cable
- Dimensions: 200mm (W) x 110mm (H) x 335mm (D). Depth includes speaker terminals
- Weight: 7kg
The DAC from Moma-Mola has been designed from the ground up using circuits and digital algorithms developed entirely in house. The converter is a three board stack that fits in one of the option slots in the MAKUA preamp. On the first board, all incoming digital audio is upsampled to 3.125MHz/32 bits and converted to noise shaped PWM. The two remaining boards are mono DACs, in which a discrete 32-stage FIR DAC and a single-stage 4th order filtering I/V converter convert the PWM into analogue with a 140dB SNR. This is near the theoretical limit for 24-bit files and far beyond that of even quad-speed DSD.
- Inputs: XLR, Optical, USB and Bluetooth (A2DP)
- Supported formats: PCM up to 384 kHz /32 bits (>192 kHz and >24 bits only via USB); DSD up to quad speed (DDSD and up only via USB)
- Performance: Signal to Noise Ratio: 140 dB (standalone version), 130dB (preamp option board); THD, IMD: negligible – estimated around -150dB.
- Bandwidth: Up to 80 kHz. Choice of sharp or slow upsampling filters, minimum or linear phase.
- Integrated jitter: <1 ps from 10 Hz upwards, <300 fs from 1 kHz upwards.
- Jitter rejection: >80 dB at 1 Hz after 20 seconds of lock.
A standalone version of the Mola-Mola DAC is in the final stages of development
The RIAA add-on for the MAKUA Preamp has MC/MM input stages are optimised for current noise and voltage noise respectively.
Unlike the more common arrangement of MC head-amp feeding the MM stage, the two stages are fully independent, realising an equally short signal path for both. Input gain is switchable in 5dB steps over a 40dB range. Input resistance and capacitance are individually switchable. Available EQ settings cover practically all known cutting curves ever used, including most 78RPM.

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).
