Tone Audio

Based around an XMOS receiver chip, it complies with USB Audio Class 2.0 (UAC2) and therefore works with native-mode USB audio drivers.  This allows plug-and-play operation for Windows, OS X and Linux operating systems.  (As it’s not UAC2-compliant, Windows requires additional drivers to handle anything above 24/96.)  Like its predecessor, the new hiFace Two parses data up to 24/192 with each sample rate family—44.1/88.2/176.4 and 48/96/192—which is handled by its own oscillator.

Listening to this new model is reminiscent of spending a week or two with Musical Fidelity’s original V-LINK: a small improvement over the USB implementation found in the Peachtree iNova, but not as musically emphatic or engaging as Philip Gruebel’s little grey box.  The Audiophilleo also scores another point over all the competition by negating the need for (and expense of) a digital coaxial cable.

Once you accept the halfway-house nature of the hiFace Two solution, the fun begins.  Meandering through Leonard Cohen’s much-underrated 2001 “comeback” album, Ten New Songs, a sense of player space is more apparent with the new M2TECH device than without.  Better clocking (i.e. less jitter) takes the listener deeper into the music.  Even at this less-expensive end of the USB-converter market, improvements can be heard in terms of micro-dynamics and vitality—Cohen’s aging croak simply sounds more human.

Switching to something of an edgier ’80s mastering job with R.E.M.’s Green exposed an over-enthusiastic lower treble in brighter systems.  This was easily dialed back, thanks to Hannes Fricke’s adjustable tweeter gain on his WLM La Scala floorstanders, but the titanium dome tweeter in a pair of (vintage) Celestion Ditton 11 required a more creative solution.

I installed the original hiFace yesterday - and it sounded pretty decent, decent enough I decided I would be buying one or the other. Not as good as the source CD, but good nonetheless - certainly hugely better than the lappy's headphone output! For me to stump up the considerable extra for the hiFace Two it would really need to be clearly better...

I installed the hiFace Two today - it sounds better, MUCH better. Not a little tiny in-the-imagination bit better - MUCH better. It sounds pretty much as good as the source CD - though I'll be doing some more listening to confirm how things rank.

I didn't expect this. I thought they'd sound the same - thought using a cheap interconnect as a digital coax, my lappy with its very noisy PSU, and Windows Media Player, would more than obscure any differences, but they don't and the improvement between old and new shines through.

Can you improve the best? We did it! The new hiFace Two makes it easier to achieve the best sound off your computer. Thanks to USB 2.0 Audio compliance, no drivers are required anymore with Macs;

ASIO can be used under Windows and Linux is supported also! Performance is enhanced thanks to the new output circuit which is compliant to S/PDIF physical standard. No more clicks and pops when skipping tracks.

hiFace Two unveils you a whole new musical world at high resolution!
DETAILS

Highest quality digital audio up to 192kHz/24bit S/PDIF audio format available from your PC, MAC or Linux computer. Very low jitter oscillators, asynchronous transfer on USB.

Compact size (2x2.2x10.2cm) with hi-end performances hiFace Two USB interface has been conceived to further improve the performance and ease of use of the acclaimed and award-winning hiFace. hiFace Two input format is a data stream signal with sampling frequency/resolution up to 192kHz/24bits, compliant to USB Audio 2.0 specifications, available from a PC, MAC or Linux computer USB port. A very high quality S/PDIF stereo audio output signal is available from hiFace for your Hi-Fi system DAC (Digital to Analog Converter). HiFace looks like a small USB pendrive, featuring a very compact size. Internal very low jitter oscillators allow for playing 192kHz/24bits audio files that feature the best signal quality. hiFace Two is even easier to use than the hiFace. No drivers are necessary with either Mac and Linux computers, while a single standard driver is required for Windows computers. While the old hiFace offered Direct Sound, Kernel Streaming and WASAPI transfer modes, hiFace Two adds ASIO mode to enable interfacing to pro players and software tools. hiFace improves the audio performance over the hiFace by a new output circuit compliant with S/PDIF levels, linear regulators in place of switching ones and a clickless operation even when skipping tracks.

FEATURES:

1) LOW JITTER, LOW PHASE NOISE, HIGH STABILITY OSCILLATORS

Most audio interfaces and USB-provided DACs refer the data stream clock to the same USB interface clock, that often suffers a very heavy jitter (short range oscillator frequency variations). Thanks to two quartz precision oscillators used on M2Tech hiFace, clock source for output data stream features a very low jitter. A more stable clock is recovered by DAC S/PDIF receiver; a low jitter produces a very limited sound image distortion and degradation. Phase noise (main responsible for jitter) is also very low: this guarantees a short and long range clock stability, also reinforced by a board supply voltage regulation (e.g. at environmental temperature stability is 2-5ppm approximately, compared to 50-100ppm performed by oscillators normally used on commercial CD players).

2) USB 2.0 AUDIO COMPLIANCE
No more needs for custom driver. Using the hiFace Two is very easy. Just connect it to your Mac or Linux computer and it will be immediately visible in the devices list and ready to use. A driver is still necessary for Windows computers, which enables for DS, KS, WASAPI and ASIO mode.

3) COMPACT SIZE AND EASE OF USE
M2Tech hiFace features a very compact size and can be directly (or using an accessory USB A-A adapter, not supplied with hiFace) connected to a High Speed USB 2.0 port of any computer. A very high electric and mechanical performance RCA gold connector provides an output signal, ready to be connected to a Hi-End system. No external power supply is required, as hiFace draws its power from USB bus itself and regulates it with its internal regulators. hiFace USB interface connected to a last generation mini PC provided with a High Speed USB port makes for a complete music transport system at very low prices (in the range of few hundreds Euros). Such system allows for listening any density and resolution music files, playing own CD's using a CD ROM drive, obtaining access to more than 10,000 web radio, many of which broadcast their transmissions with CD quality.

"It's really is an excellent converter all by itself, with no external clock or battery power supply added. It performs very well and is easily comparable to the most expensive USB-S/PDIF converters known to me. It may not always win but won’t always lose either. Adding the battery power supply changes the way it reproduces acoustics, space and the drawing out of shapes. The stage moves a bit further away and has a more natural perspective, better extracted reverbs and flavors. It is not better or more ‘detailed per se. It may even seem that the AC mains brings out more details. With the battery supply here is instead greater wealth. It's like with Harbeth speakers. To those used to chirping tweeters they may seem dark and less detailed. For those cured of these artifacts of hyper detailed—of course in my opinion only—they are simply natural and everything else is warped. So it is with the hiFace EVO. Adding a better power supply highlights this difference.

"This review is primarily focused on the hiFace EVO DDC which converts USB computer signal into any of the five types of signals ‘understandable’ to a classic D/A converter: RCA, BNC, TosLink, I²S, AES/EBU ST. Its operation can be further improved by applying the EVO Supply, an external battery PSU and, through the BNC input, adding the EVO Clock, an external precision master clock. I also tested those two devices".

"I mainly compared the Italian converter against the—in my opinion very successful—asynchronous 24/192 input of the Wyred4Sound DAC2 [that is based on an OEM hiFace board from the EVO's designer - Ed]

Listening (HiFace Evo + Evo DAC)

With the laptop serving lossless files, I connected the HiFace Evo and the Evo DAC with a Cat 5 cable to get the zero-jitter advertised by M2Tech. I set the Audio MIDI Setup in OS X to match whatever source material I played (44.1/16 or 96/24).

Vocals were real-life smooth and the Evo DAC squeezed every last bit of nuance out of the bitstream, even on 44.1/16 material. I had a hard time reconciling the analog-like sound that I knew was originating through a USB data connection. It will be hard to return these units to Italy.

Listening (Sony DVD player + Evo DAC)

As expected, 96/24 sources lit up the “48” and “X2” LEDs on the Evo DAC.

My Sony DVD player can play 96/24 LPCM discs burned from high-resolution downloads. Until listening to the Evo DAC, I had always been happy with the sound of the Sony’s stock converter. The Evo DAC revealed depths that I didn’t know existed in the source material. I didn’t realize this humble DVD player had such big sound trapped within it. In every case, the Evo DAC sound was fuller and wider than what I heard from the stock player’s analog outputs. I only have two speakers, but the sense of surround sound was always better with the Evo DAC. The top end went higher, and the lows went lower. I could hear more detail, but without harshness, sort of like the sense of relief one gets by pulling the grilles off speakers"

Hi-End S/PDIF Output Interface

DETAILS

hiFace Evo by M2Tech is the new statement in high quality computer audio interfaces Hosted in a compact and stylish aluminum case, hiFace Evo is capable of flawlessly transfer audio data up to 192kHz, 24 bits to virtually every DAC or A/V receiver around, thanks to its comprehensive outputs set hiFace Evo incorporates the same leading edge technology as the classic hiFace – with some plus Asynchronous operation up to 192kHz is used in conjunction with proprietary drivers which allow for Kernel Streaming, Direct Sound and WASAPI operation (the latter under Windows vista and 7) Windows and Mac drivers are already available Very high precision, very low phase noise (jitter) crystal oscillators are used To further improve their performance, they have a dedicated shunt voltage regulator which ensures a very low noise and spurious-free supply hiFace Evo is powered by an external power supply (included), to avoid the dirty USB bus supply from negatively affecting hiFace Evo’s performance Linear regulators are used all around, to allow all jitter-sensitive digital circuits to operate at their best Also, a low-pass filter is provided at supply input to further reduce any bad influence from the supply hiFace Evo can be powered by an external wall adapter (9V 1A will fit), or with a 9V alkaline battery, or with a 72V/108V Lithium battery Several outputs are available at the same time: coax on RCA, coax on true 75 Ohms BNC, AES/EBU on male XLR, optical on Toslink™ (Toslink™ is guaranteed to operate up to 96kHz, though we got operation up to 1764kHz on certain setups), optical on ST (for high-speed operation up to 192kHz and up to 16km or 1 mile), straight I2S for direct connection to DIY DACs on RJ-45 (NOT plug-in compatible with NorthStar products!)

All outputs, except straight I2S, are galvanically isolated (coax and AES/EBU via a pulse transformer) AES/EBU output can be set to professional or consumer mode by an internal jumper In addition, an input for an external clock is available, for those who have a extremely precise and stable clock generator to be used with hiFace

Evo hiFace evo automatically recognizes the presence of the clock on its input and switches on it whenever available This input is also galvanically isolated via a pulse transformer Three LEDs indicate power, external clock presence and incoming data from the PC Connection to the PC is via a type B female USB connector

PROPRIETARY DRIVERS

The standard audio drivers available on the market (eg Microsoft Windows operating system) dictated constraints can be overcome thanks to hiFace proprietary drivers: they allow for transferring audio data, maintaining the original file quality without any loss of resolution quality; also, sampling frequency constraints are overcome, while Microsoft and ASIO drivers oblige to operate at no more than 96kHz When hiFace is used together with a player application such as FooBar (available for free on Internet), you can transfer S/PDIF stream music files to a D/A converter at 192kHz/24bits maximum frequency/resolution, avoiding undesired PC or MAC audio mixer data processing during the data transfer from hard disk to interface Presently, Windows XP, Vista, Windows 7 drivers are available, as well as Mac drivers for 104, 105 and 106

JKenny HiFace mod with battery supplies rocks!


"My Hiface was commissioned last night by myself and friend who bought the same unit John configured everything for plug and play with the two LiFePO4 batteries After reviewing the documentation he supplied the table gave everything we needed, and conveniently enough the outputs match the Buff2 DAC (however don't need MCLK) She fired up immediately after installing the driver No issues whatsoever

There are some slight improvements to his documentation I have suggested and I believe these will be done shortly

It was immediately obvious that the Hiface is distinctly better than the dddacde USB-I2S convertor (which has a Guido Tent X02 re-clocking 12Mhz into it) in several ways:

Far more transparent - I was able to detect many subtleties in recordings I had not heard before, like felt pedal action on a piano and other instrument interplay previously obscured

Improved tonality and expression - related to the above, better ebb and flow, more dynamic shadings and expression heard in voices, and instruments

Slightly better top end resolution - again related to transparency, and making shakers sound like shakers

Improved pace, rhythm, and timing - not expected, but very much welcomed

And this was without the galvanic isolation included!

Conclusion - I expected I would struggle to hear the difference between the dddacde USB-I2S converter and the Hiface On the contrary, the differences are bleedingly obvious This is perhaps the best bang for buck I've ever experienced in hifi - a truly amazing sonic improvement."

Evo Supply
High Performance Power Supply

DETAILS

Evo Supply is a battery-based high performance power supply It’s the perfect companion to the hiFace Evo and other 9V-operated M2Tech devices

Evo Supply features a Li-Ion battery with 2200mAh capacity (minimum), an integrated battery charger and a low-noise regulator which is used to provide current to the load while the battery is being charged, thus ensuring continuous operation to the load Charge time is about three hours, the best choice to ensure a long battery life

Evo Supply delivers up to 1A (peak) on 9V (low-noise regulator) or on 95V to 11V (battery) Two outputs are available for more versatility A switch allows for turning the load off when not used to save on battery charge Another switch allows to select the operation mode: automatic charge or charge inhibit Two leds indicate the presence of the wall adapter and the charge in progress In automatic charge mode the battery charger starts charging the battery every time the battery voltage drops below a low threshold During the charge, the low-noise regulator feeds current to the load At the end of the charge process, the output reverts to the battery In charge inhibit mode, the battery is used down to the low threshold and then the load is disconnected to avoid excessive depletion Charge is then started by switching to automatic charge mode The battery is protected against overcharge, overcurrent and excessive depletion A 15V/2A detachable wall adapter provides current for battery charging and load powering when the battery is being charged The user may disconnect the wall adapter after battery is fully charged in order to reduce interferences to a minimum

  Portion of th review Translated from Italian to English

"The Young gives immediately the impression of a sound relaxing, we would dare to say analog, simply maintaining a high transparency; in fact, the transparency is actual an of the features that marks this converter. The reconstruction of the sound stage is excellent; the expansion is spacious and enough deep, so like the focus. With a very fine grain, the Young is very pleasant to the listening and did not show marks of spigolosità and/or harshnesses... is fluid.

The low range is very neutral, deep and articulated and not show you mark of "dryness", with a round lower part accompanied from an acceptable punch. The shouting are full-bodied and the you surround very definite; the feminine shouting I am very extensive, without marks of yielding. Also the high range is clear... crystal clear and comes intended precisely in second plan, facilitating the correct interpretation of the resonant plans"
