The superb M2Tech HiFace2 USB/S/pdif converter.
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 specificastions, 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.
