ETAL Group today unveiled a Class D amplifier in a format smaller than a business card – opening the way to highly compact lifestyle electronics, networked audio and battery powered applications. z0702ana-ala0080-class-d-amplifier-from-anaview

Stefan Ruuth, Sales Manager at ETAL, said, “In terms of size-performance, the Anaview ALA is unmatched, delivering amazingly clean and room-filling sound from a very small module.  We’ve already seen a lot of interest from designers of networked audio devices, portable audio devices, docking stations, audio receivers, powered speakers and residential audio systems. It’s perfect for applications that need great sound but where space and/or power are limited.”

With overall dimensions of just 68mm x 33mm x 18mm, the ETAL Anaview ALA Series delivers 2 x 45Wrms into 6 Ω. It is designed for board to board mounting and can be powered by a single voltage of 12-25V DC making it easy to integrate. The Anaview ALA has an 80kHz load independent frequency range (-3dB) and a 115dB dynamic range with low Total Harmonic Distortion (THD) throughout. Features include an entirely differential patented Adaptive Pole Control (APC) amplifier technology.

The Anaview ALA can be supplied from a simple single voltage AC/DC power supply, commonly available at low-cost, alleviates end-product UL-certification. Alternatively, the low power draw and single-sided supply means that the module is also compatible with Power–over-Ethernet (PoE) for commercial network audio applications where audio and power are provided on a single Cat-5 cable. Equally, it can be easily integrated into battery–powered and rechargeable products.

TRINNOV Audio is introducing the new Amplitude8 power amplifier at CEDIA 2016.Trinnov-Amplitude8_front-black-half

With two large, linear power supplies, each with its own toroidal transformer and dedicated power cord, each of the eight channels of the Amplitude8 can deliver up to 500 watts rms at 2Ω. Perhaps more importantly, any single channel associated with either power supply can deliver 1200 watts peak power to handle transients.

The amplification stage of the Amplitude8 features the industry’s lowest-distortion and noise specifications say the company, and what little noise there is remains frequency independent with a s/n ratio of -125 dB..

As you might expect, the Amplitude8 integrates seamlessly with the Altitude32 AV preamp which was launched back in June and supports Dolby Atmos®, Auro-3D® , DTS:X® and has just been selected the Best Product 2016-2017 in the High-End Home Theater category by the European Imaging and Sound Association.

A full 32-channel system including the AV preamp and all amplification requires less than 20U of rack space, yet delivers almost 10,000 watts of power at 8Ω.

The Amplitude8 is made in America and available now. MSRP is $13,500.

Chord Electronics’ new SPM 1050 MkII power amplifier, first unveiled at High End 2016, Munich, is now available worldwide. The new MkII version directly replaces the original and introduces the latest Chord amplifier technology, plus some key aesthetic improvements.SPM1050M2BLKF3qtrWHT_B_online

The latest-spec MkII model offers reduced output distortion plus improvements to capacitance for cleaner power delivery. The second-generation version also includes enhanced isolation on the mains transformer to reduce interference. In keeping with the original, the SPM 1050 MkII uses Chord’s low-distortion amplifier circuitry and features four proprietary lateral-structure dual-die MOSFETs per channel (eight in total).

The SPM 1050 MkII offers both balanced XLR and RCA phono inputs, plus two pairs of loudspeaker outputs with gold-plated connections. A single power button offers operational simplicity from stand-by mode and the amplifier’s status is indicated on the faceplate by a simple two-LED sequence showing power and relay functions.SPM1050M2BLKFrontWHT_online

Aesthetically, the MkII version includes a new vented aluminium lid, akin to the DSX1000 streamer, plus a new piano-black acrylic side-panel option giving the power amp a fresh, contemporary look. Additional options include a choice of finish for the established Integra leg system supports, these include: nickel, satin-black anodised and aluminium. 

As with all Chord Electronics amplifiers, the new SPM 1050 Mk II features Chord’s proprietary 2KW high-frequency switch-mode power supply, which was originally developed for use in aerospace, telecommunications and data processing, where quality and power is needed in a very space-efficient design. The technology allows instantaneous power to be taken from both power rails simultaneously when the audio track demands.

The technology is complemented by a large bank of energy storage capacitors that are ‘recharged’ by the power supply many thousands of times a second, giving the amplifier huge reserves, plus the ability to react effortlessly to any signal. This configuration gives increased voltage swing, greater dynamic range, plus the ability to cope with even the most demanding loudspeaker loads. Unobtrusive protection circuitry constantly monitors the amplifier status and magnetic current-sensing will shut down the SPM 1050 MkII in the event of a short circuit, or DC overload.

The Ultra High Frequency power supply is a self-contained, self-monitoring module, which is common to all Chord amplifiers and is fundamental to their exceptional performance. A sophisticated mains input filter ensures that the power supply is exceptionally well shielded from disturbed mains input, and more significantly, the mains itself is completely untouched by emissions from the amplifier.SPM1050M2BLKrearWHT_online

The NS-6170, equipped with Google Cast, AirPlay, Spotify, Wi-Fi, and HDD-ready USB input, is based on a twin-monaural L/R channel layout with separate power supply paths, discrete custom capacitors for each channel, and dual-differential 768 kHz/32-bit AK4490 DACs to decode the positive and negative halves of the signal waveform.  Onkyo-NS-6170-Network-Audio-Player

Developed by Onkyo’s R&D team after years of exploratory research into Hi-Res Audio, a new wideband DIDRC Filter replaces the standard DAC output filter, eliminating ultra-high-frequency distortion inevitably generated as a result of the digital-to-analogue conversion process, says the company’s recent press release.

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.  25101915609_b257e6209b_k

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. 

UK retail price (inc VAT):

Makua – £7,299; Kaluga (each) – £4,999; DAC board for Makua – £3,999; Phono stage for Makua – £1,699

Now in its 81st year, Quad has been making valve amplifiers for home use since the late 1940s. The company’s latest model, the VA-One, brings the concept bang up to date; a compact integrated amplifier that fuses Quad’s traditional valve-based audio expertise with modern digital audio streaming.4558_Quad_VA-One_ONLINE

With a footprint measuring just 18x33cm, the VA-One is very compact for a stereo valve amp – sufficiently small to sit comfortably on a desk.

Three digital audio inputs – optical, coaxial and asynchronous USB – support data up to 24-bit/192kHz, and an RCA-phono input gives the option to connect an analogue source like a CD player or a turntable (when used with a suitable phono stage). In addition, 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 preamp section incorporates an ECC83 high-impedance triode, feeding an ECC82 twin triode driver and phase splitter stage. The output stage uses two EL84 pentodes per channel in push-pull configuration, delivering 2x15W.4559_Quad_VA-One_(rear)_ONLINE

External styling is classically Quad, finished in traditional ‘Lancaster Grey’. The amp’s front panel sports a smooth-acting volume control incorporating a motorised potentiometer, allowing adjustment via the supplied remote control, together with a headphone output and controls for input selection and Bluetooth pairing.

The Quad VA-One integrated valve amplifier is available from mid-August, priced at £1299.95 (RRP). It joins the similarly styled PA-One headphone amp in Quad’s expanding ‘One’ range of valve-based amplifiers with integrated DAC circuitry.

First Watt’s new F7 power amplifier (MSRP: $3,000) is a very unique power amplifier says the company’s press release that’s just landed at Hifi Pig. It’s a two-stage push-pull JFET (input)/MOSFET (output) topology with fewer parts than any First Watt amplifier to date. The new F7 has been created as an updated version of the earlier F5 amplifier. Conceived in 2007, the F5 was a push-pull Class A amplifier employing eight semiconductors and 23 resistors to achieve 25 watts output with good specifications and good sound. Nelson_pas_F7_power_amp_1

According to Nelson Pass: “The F7 bests the earlier F5, comprising even better sound and even simpler circuitry.”

Like all First Watt designs, it is a relatively low power (25W/channel into 8-ohms) simple Class A circuit, designed with an unusually low parts count. It is the 19th product from First Watt, since its founding in 1998 as Nelson Pass’ “personal laboratory”.

Explaining First Watt, Nelson Pass says: “I spend a lot of time building and evaluating basic amplifier concepts with an eye toward producing the highest quality sound with elegantly simple circuits.

There is no such thing as a perfect amplifier, but there is a best amplifier for each type of speaker, music, and listener. Each First Watt model is a unique design and is ‘best’ in some particular way. They look alike because they all use the same basic chassis and power transformer. On the up side, it makes it easy for me to test ideas and compare different designs with the hardware being a fixed constant.

Looking for tomorrow’s faceplate with yesterday’s circuits? You’re in the wrong place.”

The desire for a simpler circuit is self-explanatory – apart from the aesthetic, Nelson Pass believes that that simpler circuits tend to sound better: “In such a simple circuit, there are opportunities for improving performance by careful choice of transistors, resistor values, voltage and current values and precise matching of parts.Nelson_pas_F7_power_amp_2

The F7 has most of what was on his Wish List:

Very wide bandwidth

Low distortion and noise

Large Class A operating region

Less feedback

No degeneration in the output stage

Very low thermal distortion and drift

No capacitors or transformers (apart from the power supply)

Uniquely, it incorporates a very innovative balance of very low Negative Voltage Feedback and a small amount of Positive Current Feedback to give an “astonishing measure of control over reactive loudspeaker” loads.

Modest amounts of Negative Feedback are balanced in counterpoint to a small amount of Positive Current Feedback, creating an equilibrium where the output impedance approaches zero, improving transient and frequency response. “Of course you can achieve a similar effect with tons of negative feedback, but I think this is more elegant and sounds better. For brevity, I call it ‘PCF’,” explains Pass.

Also, I put more capacitance in the power supply and found a clever way to further reduce the effect of high frequency DAC noise and environmental RF. This is a different amplifier. The diversity of audio taste being what it is, not everyone will prefer it. I presume that a certain segment of audiophiles will like it.

Audio Research has announced the introduction of their Foundation Series. From the same engineering and design team responsible for the Reference Series, “the Foundation family of vacuum tube components has been created to provide incredible musical experiences”.4476_Audio_Research_Foundation_Series_(stack_without_shadow) (1)

The first three components include the LS28 line stage preamplifier, the PH9 phono stage, and the DAC9 digital- to-analog converter. A new amplifier will follow, with other products to complete the series. All models will be available in both black and natural anodized aluminium finishes. Each unit comes with its own custom metal remote control.

All products at Audio Research follow the exact same path from concept to production, regardless of the series or model. The Foundation Series shares the same lineage, build quality, and many design characteristics found in the more costly Reference Series.

Many of the parts in an Audio Research product are proprietary, while some are designed for a singular model. This attention to detail is inherent to all processes at Audio Research – from the hand-soldering of every circuit board, to the final listening test which is conducted by the same person who helped guide the design. Our commitment at Audio Research is to deliver the most musically satisfying experience at every level.

The LS28 line stage is a flexible  preamplifier. Four balanced and four single-ended inputs, and two sets of both balanced and single-ended outputs, allow maximum connectivity. The straightforward menu allows control of numerous parameters, including input naming, tube hours, auto shutdown, and home theater passthrough. Phase invert and mono are also standard functions. At the heart of the LS28 are four 6H30 vacuum tubes in the analogue circuit.4471_Audio_Research_LS28

While the LS28 is the perfect match for any Audio Research amplifier, it has been designed to work with nearly any amplifier on the market today. Shipping to begin in June.4472_Audio_Research_LS28_(internal)

The PH9 phono preamplifier is a great pairing with most cartridge and turntable combinations. A trio of 6H30 vacuum tubes are at the core of a simple and clear signal path to provide the most transparent preamplification possible. Five different impedance settings allow for cartridge loading, which can be changed on the fly with the included metal remote. Cartridge impedance, tube hours, auto shutdown, and other features are included in the menu system. Shipping to begin in July.4474_Audio_Research_PH9

4475_Audio_Research_PH9_(internal)

The DAC9 digital-to-analog converter decodes most current formats with state-of-the-art vacuum tube technology. Five digital connections – USB, RCA, BNC, AES/EBU, and Toslink – provide connectivity to all of your digital sources. Quad DAC architecture provides a balanced digital signal, wide dynamic range, and decoding resolutions from red book CD up to 384 kHz and native DSD sampling rates.4468_Audio_Research_DAC9 (1)

A pair of 6H30v vacuum tubes are the heart of the analog circuit. Both balanced and single-ended connectors are provided for output connectivity. Native-rate upsampling and selectable digital filters allow customisation of the digital signal. Shipping to begin in August.4469_Audio_Research_DAC9_(internal)

The MQ-300 is a new generation of vacuum tube stereo amplifiers from LUXMAN that “uses the most thoroughly selected parts and circuits to maximise the performance and tonal quality of the latest direct heated triode – the TA-300B”. Following in the design footsteps of the MB-300 released 31 years ago, the MQ-300 combines traditional design with cutting edge technology.   MQ-300_skew_coverlesss

Since the foundation of the company 90 years ago, and the subsequent release of the MB-300, LUXMAN has pursued certain core principles for sound generation. These principles are embodied in the MQ-300 as ‘honest and natural sound quality, feeling the sound field without exaggeration’, ‘feeling the unity of sound with sufficient data for the whole audio band’ and to achieve ‘fatigue free listening enjoyment’. Expressing the original sound whilst bringing the spirit of each disk to life are qualities intrinsic to the MQ-300 and those principles.MQ-300_rears

Design History

The MQ-300 is based on the cosmetic design and circuit configuration of the MB-300, the renowned vacuum tube monaural power amplifier released by LUXMAN in 1984. The elements of traditional design and elegant tonal quality that is unique to the performance of the TA-300B, a direct heated triode, have been maximised in the MQ-300.

Mitchell and Johnson’s trio of CD Player, Amplifier and Streamer cost a total of £947 which puts them very much in the budget category but can they satisfy sonically? Dominic Marsh finds out for Hifi Pig.  More »

Introducing Billie, the stereo amplifier that combines  the precision of digital with the warmth of analogue sound in a Nordic minimalist aesthetic. An objet d’art designed with attention to detail inside and out, Billie brings back the transcendent ritual of listening, say the company launching it on Kickstarter.heaven_11_kickstarter

“Our goal is to go beyond soundbars and bluetooth speakers, back to how music was meant to be experienced.” says Itai Azerad, Heaven 11 cofounder and designer. “We believe that the stereo system is still the best way to experience that ‘live in the room’ feeling. We’re not about ‘multi-room’, we’re about ‘in the room’.”

Named after Jazz Icon Billie Holliday, this amp plays ALL your music beautifully whether it’s from your phone, TV, Spotify or vinyl.heaven_11_kickstarter82

“We designed something for the pragmatic audiophile because we couldn’t find it out there. We built an affordable high-caliber amp that plays all of your music collection –  be it vinyl, Hi-Res digital, line or wireless.”

Combining the detailed soundstaging of digital to the round, analogue smoothness of tubes, Billie features ICEpower amplification by Bang & Olufsen (120W/4Ω), 32bit/384Kh DAC, AptX Bluetooth, RCA, vinyl and Toslink inputs. It comes with a custom-built tube preamp and a powerful headphone amp. The amp is to be manufactured in Montreal, Canada.

Moving away from the current trend of generic design and disposable materials, Billie’s shell is made of thick, machined aluminium. The cool minimalist casing details are balanced by warm, crafted hardwood knobs.

“Design is not just aesthetics, it’s how we use an object, what the object communicates to us and about us.  I believe a stereo’s design ought to be closer to an electric guitar than a cable box -what most stereos look like these days. An electric guitar is quite a functional tool, -not too many useless knobs on there- but it’s also such an intimate object, there’s a mystery about it, you gotta feel a connection, you gotta want to touch it.”

Billie is to be launched on Kickstarter mid-July at the special price of $595 US. After the campaign, the price will be $895/$995 US.

Heaven 11 Audio is a Montreal-based audio company  founded in 2015 by Itai Azerad and Andre Keilani, two award-winning product designers with a lifelong passion for music.

Roksan Audio is adding the blak series of components to its portfolio. The blak series is being introduced as an entirely new design for Roksan – both in terms of sound performance and visual appeal. Featuring a robust, industrial design the blak series is the audiophile solution for those seeking “superlative performance and features within a ‘statement product’ aesthetic, but without the esoteric high-end audio price tag” say the London company’s recent press release.

Handmade in the UK and at a specialised facility in Germany, the range is initially launching with an integrated amplifier and a CD player. These will be followed over time a comprehensive range of products that will offer the same performance-for-cost ratio.

Like the K3 range before it, all blak products will be available in three finishes – Anthracite, Charcoal and Opium – and all will be supplied with a stylish and intuitive system remote.

blak Integrated Amplifier

The blak Integrated Amplifier combines a high-end amplifier with a highly-specified USB DAC, a Bluetooth receiver and a dedicated headphone amplifier; all in one sleek chassis.charcoalblakamp1

The amplifier section of the blak Integrated Amplifier uses hand- selected audiophile components throughout its circuitry, including high- quality relays. The chosen transformers are also tuned to ensure the best sound quality and current power available. This sophisticated internal design allows the amplifier to deliver > 150W (8Ω) output.

The blak Integrated Amplifier boasts sufficient inputs to cater for almost any high-end audio system. Alongside three RCA pairs, there’s also a balanced XLR pair input for superior source devices. There’s  also a Moving Magnet-compatible phono stage inside.

For ease of use, the blak Integrated Amplifier supports wireless music playback via its built-in aptX® Bluetooth module. This allows for up-to CD-quality wireless streaming from compatible laptops and smart devices. For more advanced digital media, the amplifier also boasts a USB (Type-B) digital  input for playback from a computer or laptop. The DAC allows for playback of audio files up to 24-bit/192kHz (PCM) or DSD128, offering an exceptional high-resolution performance.blakampback

Finally, whereas many other products include headphone inputs as an “extra”, Roksan have gone one step further with blak. Here the headphone amplifier sits within its own dedicated section, with an independent power supply and toggle switch.

Operation of the blak Integrated Amplifier is effortlessly simple either via the supplied system remote or through the front panel. The large, clear to read (yet dimmable) LED display shows the selected input and the over-sized volume knob has a visual indicator around its circumference to indicate the volume level.

Audio Hungary are a relatively new name to Hifi Pig and we first met them at this year’s High End show in Munich where they had their wares on display. This, the Qualiton A20i, is their entry level integrated amplifier. It is very compact, runs 2 x 20 Watts of Class A power and is based on classic push-pull topology.

It arrived, with little help from DPD, in a sturdy double (and surprisingly heavy) boxing, with the amp inside being very well packed indeed. The first thing out the box was the remote…wow, that’s heavy and really rather beautiful! Off with the valve cover to expose the tubes and the gleaming chrome body-work and that’s it all unboxed.
