Westminster Lab makes no claims as to how good it is, rather just invite you to enter into their ‘new dimension’ of music experience. According to them words are totally futile. But that would make for a short review, so, not known for keeping quiet, Janine Elliot wanted to tell readers about this unique amp costing £32 000. More »

roksponsmallChord Electronics is showing its new TToby power amp for the first time in the UK at The Indulgence Show (14-16th October). The new TToby is a 100-watt stereo power amplifier and has been designed to complement the Hugo TT DAC/headphone amplifier.

roksponsmallHand-built by ATC in the UK, the P2 class A/B stereo power amplifier is designed to complement the brand’s range of hifi preamplifiers aesthetically and operationally. Rated at 300W continuous power per channel and developed in tandem with the P2-Pro studio amplifier, the ATC P2 is a Dual Mono design, keeping the power supplies, signal and return paths discreet. This approach ensures that the amplifier will achieve the maximum signal separation with minimal crosstalk, and that inter-modulation between channels via the power supplies is reduced to an absolute minimum across a frequency range of 400kHz. It also means that the power delivery from one channel cannot affect the specified power available from the other.

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.

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.

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


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.

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.

SRP £2,750.00

blak CD Player

Internally the blak CD Player uses a totally isolated disc mechanism to eliminate vibration. Once extracted from the disc, the digital signal is managed by a DAC chip-set for bit-perfect conversion and an advanced digital clock for optimal performance.Roksan-blak-CD-Char-Left

For connecting to an external DAC there are three digital outputs available (S/PDIF, Optical or AES/EBU), or for connecting straight to an amplifier – like the blak Integrated Amplifier – there’s the choice of either unbalanced RCA or balanced XLR outputs. Once connected, the whole player is controlled with the supplied system remote or via the front panel; additional handy information is displayed on the dimmable  LED display during playback.Roksan-blak-CD-Rear

Swiss manufacturer Soulutions have been in touch to tell Hifi Pig about their new 511 amplifier that will start production in October 2016 and will cost 24500CHF (around £17000). The 511 has the same switched-mode power supply found on the company’s 7 series products and is optimised for audio use.

The 511 can be used in three distinct modes:

Stereo-mode (150W @8Ohms, 300W @4Ohms and 600W at 2Ohms)

Dual-mode which gives the same results as above.
Mono-mode (600W @8Ohms, 1200W at 4Ohms and 2000W at 2Ohms)soulution_511_1604_001

The amplification circuit is similar to the 711 and 701 amps from Soulutions having at its core a proprietary voltage amplification stage that consists of linearized amplifiers operating up to a cutoff frequency of 80MHz. The Class A operation is supplemented by 500 000 µF of capacitance storage in the power supply

There are a total of 10 power supplies in the 511with those supplying audio and digital circuits being isolated from each other with optocouplers.

Quad celebrates 78 years in business this year and with the launch of Vena: a compact integrated amplifier sporting a wide range QUAD_VENAof digital and analogue inputs, plus wireless streaming over Bluetooth with aptX support.

Just 313mm wide, the diminutive Vena updates the familiar Quad aesthetic, yet remains distinctly ‘Quad’. A row of source-selection buttons and a large volume control adorn its fascia.

Vena’s built-in DAC (Digital-to-Analogue Converter) incorporates the same 24-bit/192kHz chipset used in the company’s flagship Platinum CD plus a Class AB power amplifier section and a headphone source too.

Simplicity is key to Vena’s design say Quad and their engineers selected Bluetooth wireless transmission to ensure compatibility with the widest possible range of devices, and pairing the amp with smartphones, tablets, PCs and Macs is easy.

Inputs for digital source components comprise two optical and one coaxial, plus two asynchronous USB sockets: one Type A, the other Type B. The latter is the type most commonly used for connecting PCs/Macs to audio devices like Vena; the former allows Apple iDevices to be docked, charged and played via a cable connection. Digital outputs are also provided, in optical and coaxial flavours. Analogue signals are catered for by two stereo RCA inputs, while pre-out  sockets permit the addition of an external power amp. In terms of Bluetooth, support for the aptX codec ensures the best possible audio quality when streaming from suitably equipped devices.

Vena’s small footprint (compared to many amps in its class) allows flexible positioning and ensures the amp slips neatly into a range of environments. Vena is finished in Quad’s classic ‘Lancaster Grey’ as standard, and for those with more exotic tastes, three premium finishes are now also available – Piano Black, Piano White and Rosewood – ensuring Vena complements any domestic setting.

The standard Lancaster Grey finish has an RRP of £599.95, while the three premium finish options add £100 to the price tag.

There’s a huge problem with HD music today say Benchmark and recent advances in high-resolution digital formats haveBenchmark_power_amp well outpaced most existing amplifier technologies they say. Whilst recordings are possible that have dynamic ranges that exceed 120 to 125 dB Benchmark claim it’s hard to find a power amplifier that can deliver more than 100 to 105 dB of dynamic range. Benchmark’s AHB2 power amplifier approaches 130 dB, making it “10 to 30 dB quieter than the typical audiophile power amplifier”.

The frequency response of the AHB2 extends beyond 200 kHz, to “deliver the ultrasonic detail and fast transients captured by high-resolution recordings”. At the other end of the audio spectrum, the low-frequency response extends below 0.1 Hz. The AHB2 has a high damping factor that augments its extended low-end to deliver “solid, well-controlled bass”.

THX recently patented two new technologies that address crossover distortion, and Benchmark incorporated these innovations into the AHB2 design. These new innovations claim to virtually eliminate crossover distortion while offering opportunities to improve efficiency, damping, and dynamic range.

We’d read a good deal about the little Tisbury Mini Preamplifier and it was getting some good comments made about it so TA-mini02we thought it about time that we got hold of one for review.

“Tisbury are a small, UK based outfit that at the moment manufacture just the one product and sell direct. The Mini Passive Preamplifier is available in three flavours: Single Out – 3 inputs and 1 variable output. Parallel Out – 2 inputs and 2 variable outputs (for bi-amping). Tape Out – 2 inputs, 1 variable out and 1 fixed output. I went for the Tape Out option so that I could wire up the headphone amp into the system.

It’s a tiny little thing but it looks very nice indeed and immediately got the thumbs up from Mrs Hifi Pig. It has an American black walnut front panel on which the input selector and the volume control are mounted and round the back are the four RCAs. It looks great and also very well built in its simple anodised aluminium box.”

The Iridium power amplifier from Tellurium Q arrived a couple of months ago and has been a permanent feature on theIridium_1_small Hifi Pig rack since then.

The Iridium by Tellurium Q is a single ended class A amplifier that gives out a not massive 18 Watts per channel into 8ohms (the same as my 300B PSE amp actually). It’s a heavy beast weighing in at around 21Kg but it also looks quite elegant on the top of the rack. Now, I say the top of the rack because being class A the top of this amp gets very hot indeed (the heatsinks are on the inside of the casing) and I’d be unsure about putting it in a situation with anything directly on top of it.

The Iridium is a dual mono design where each channel is effectively isolated from the other and uses a mixture of power MOS FETs and large power semiconductors. Each channel has its own dedicated torroidal transformer and rectifier bulk capacitors for smoothing.”

Many of you will know the Onix name from the 80s and 90s, but the brand has been given fresh life in the last few years and here Jerry looks at the Onix RA125 Integrated amplifier which retails in the UK for £1975.

“Founded way back in 1979 in Brighton, England by Tony Brady, Onix was a well-known and well respected “small ra 125 b (front)English brand” in the 1980s.  The OA21 ‘shoe-box’ style integrated amp was something of a cult item and was highly regarded largely due to the excellence of its power supply implementation.
Onix dropped out of sight in the 1990s until finally being acquired by the Chinese Shanling company in 2002 where the marketing focus was the Far East and the USA. But Italian Francesco Pace then took up the reins of European distribution with his Pacetech company and a complete new line of Onix products started in 2008, encompassing amplifiers, pre-amplifiers and phono stages as well as CD players and DACs.  The Onix brand is distributed in the UK by UKD.”

Burson have announced a June launch for their Timekeeper amplifier. It is an 80W per channel Class-AB stereo Timekeepers_x2_45d_front(W)power amp which can be bridged into a 240W mono block and is the same size as the company’s Conductor preamplifier.

There is a growing community of desktop audiophiles and the Timekeeper is very much aimed at this group of users. Burson say that these audiophiles want “high-end equipment that are desktop friendly and given the compact size of the Timekeeper amplifier they will not be disappointed”.


The Timekeeper looks to be a versatile bit of kit and you can have it running in stereo, then upgrade to 2 Timekeepers as you move from a desktop system to large room listening and from RCA systems to XLR systems.


Every bit of the Timekeeper is custom designed and built to achieve Burson’s “definition of perfection”.

NuForce Inc, introduces today STA-100 stereo power amplifier. IMG_7966

Similar to NuForce’s other amplifiers, the STA-100 utilizes a Class-D design topology that delivers 160-Watts per channel. Proprietary feedback circuitry operates as the cornerstone of the STA-100’s sound quality. A self-resonant design, the 400 kHz PWM switching frequency constantly adjusts to the input signal, output current demands, and loudspeaker impedance variations.

There’s not a lot going on on the front panel and so here’s a photo of the rear of the amplifier.

Chord Electronics has upgraded its Standard Series power amplifiers to MkII status. The upgrade introduces  Chord spm1200Miiimprovements taken from the Reference Series to a more affordable line up.

Four models have been updated: three stereo power amps and one monobloc. The revisions have been implemented to the following stereo models: SPM 1200MkII (350 watts); SPM 4000MkII (480 watts); SPM 5000MkII (500 watts), plus the SPM 1400MkII monoblock (480 watts).

On the outside, the new MkII models sport a new front-panel design and rear connector plate, featuring new British-designed, heavy-duty, gold-plated insulated speaker terminals. The new rear connector plate also enables third-party power connectors to be used.

On the inside include: a new power-control and sequencing board for simpler operation and better visual indication; refinements to the filter components to ensure greater high-speed performance and overall stability; plus a plethora of circuit board and earthing changes to improve high-current power flow. Driver circuitry improvements have also been implemented, “giving a faster overall response and improved high-frequency response”.

Krell have announced today that their S-550i integrated amp will be shipping this week!S550i_Front-sm

The Krell S-550i builds on the success of the S-300i integrated amplifier and delivers 275 watts of stereo output. The S-550i is outfitted with balanced and single-ended inputs, iPod dock, and Theater Throughput™ mode. For custom integration applications, 12 volt triggers, RS-232 connectivity and rack mount ears are included. Operational parameters can be customized via the menu system that is accessible from the front panel or the included brushed Aluminum remote control.

The preamplifier section features circuit concepts from Krell’s flagship Phantom preamplifier. Direct coupled circuitry eliminates capacitors from the signal path and a custom-machined level control adjusts volume. Discrete circuitry, in a balanced topology, is afforded its own power supply regulation. All signal gain is realized using surface mount technology featuring proprietary current mirrors. Negative feedback is not used anywhere in the preamplifier. Open-loop distortion is typically less than 0.003%. The volume control is realized with a balanced resistor ladder – bandwidth and transient response of the preamp circuitry are virtually unaffected by the volume setting.

The S-550i packs 1,750 watt transformer and 68,000μF of capacitance into a 5″ high chassis. This power supply feeds classic Krell circuitry throughout the topology using only discrete circuitry. That is, the S-550i doubles its power output when a speaker’s impedance is halved. For the S-550i, the results are 275 watts into 8 Ohms and 550 watts into 4 ohms.

Bryston, LTD has announced that award-winning studio designer Carl Tatz has selected the Bryston 4BSST² stereo L_1amplifier to power the control room monitors in a studio designed for multi-Grammy®-winning engineer Bob Bullock. “I brought the first Bryston 4B to the Nashville studio scene in the ’80s. It has since become the world standard for pro studio amplification. When budget permits, I always spec Bryston for its effortless performance, high resolution sweet top and unmatched low-end muscle,” reported Carl Tatz.

The 4B is the most popular of the Squared Series amplifier and delivers 300 watts into 8 Ohms or 500 watts into 4 Ohms (900W into 8 Ohms (Bridged Mono). The 4BSST² features balanced and unbalanced inputs, selectable gain (23 or 29dB) all in a convection-cooled fully aluminum chassis requiring no noisy cooling fans. All Squared Series L_2amplifiers from Bryston are available with silver or black faceplate (3U + .55”) and in 17-inch width (without handles) or 19-inch (with handles). A rack-mountable Pro Edition is available in black. “Bryston first unveiled the 4B amplifier back in 1976. The 4B, (and all its successors up to the 4BSST²), have been adopted as the among the most popular studio reference amplifiers of all time. We are excited that both a respected designer and an esteemed engineer chose Bryston for this pioneering project.” Chris Russell, CEO of Bryston, LTD.

NuForce, Inc have announced a single-chassis integrated stereo amplifier, the IA-18. The uniNuforce_frontt incorporates  components used in NuForce’s c Reference Series products including much of the same circuitry as the P-20, the company’s most recent flagship preamplifier, a Cross Matrix Array (CMA) capacitor module, and two V3 output amplifier modules.

The IA-18 features five analogue RCA inputs and the same touch-strip control panel as that of its reference sibling. The IA-18’s volume control, which, like the P-20’s, consists of a switched-resistor ladder network consisting of the latest advances in thin-film technology is said to be a key feature of the amplifier and operates by way of a single thin-film, ultra-low-noise resistor in the signal path for each of its 0.5dB gain settings, allowing for precise volume adjustment for each channel in discrete, 0.5dB steps.nuforce_back

The amp is offered in a black or silver sand-blasted anodized aluminum case and includes a custom-designed remote that permits operation of all of the unit’s functions from listening position.


  • Full microprocessor control with memory retention
  • Five stereo inputs for complete system flexibility
  • Ultra low noise JFETs employed in input stage
  • Volume adjustment in 99 precise, 0.5dB increments
  • Thin-film switched-resistor ladder network for controlling volume – only a single resistor in the signal path at any volume setting
  • Individually adjustable volume on each input for precise level matching of all sources
  • A pair of V3 amplifier modules
  • Cross-Matrix Array (CMA) capacitor module

The NuForce IA-18 is available worldwide for a suggested retail price of US$3500 and shipping immediately.

Hifi Pig received a message from Funjoe the founder of Clones Audio in Hong Kong. Clones Audio is a one-man clonesworkshop producing amplifiers which are inspired by the 47labs gain card, so essentially gain clone products.

The story goes that one day Funjoe’s father came along to listen to his 47labs system, liked it and wanted a set for himself and so Funjoe decided to make him one for his birthday.

Funjoe says ” There are many people making the gain clone, but not many of them really get the soul of it. Many of them try to make the gain clones with audiophile parts, I tried it too but I don’t think it is better. Then I tried to do it in the simple way. After many trial and errors I have my own version of the gain clone. A new PCB layout and tiny case to make the signal path more direct.”

“For sure all of the amplifier will hand made by myself to keep the products in highest performance. I would like to sell at an affordable price so that more people can make a first step on the audio journey this wonderful stuff. Also to have my own production is my dream also.”

There are 4 power amplifiers in the range including two monos and two integrated amplifiers as well as a stereo power amplifier starting at $429.
