The hiFace USB interface was designed to obtain the highest quality digital audio signal from an ordinary PC or MAC and transmit it to your DAC with the least amount of jitter possible. Resolution up to 192kHz/24bits is available from a PC or MAC USB port with the HiFace.
Most audio interfaces and USB DACs synch the data stream clock to the same USB interface clock, that often suffers from very heavy jitter distortion. Thanks to two quartz precision oscillators used inside the M2Tech hiFace, the clock source for the output data stream features extremely low jitter (2-5 ppm vs. 50-100 ppm for most CD players).
You have the choice of a very high quality S/PDIF stereo audio output, or an equally high quality BNC output. The HiFace looks like a small USB pendrive, but features very compact, very low jitter oscillators and proprietary drivers that allow for playing 192kHz/24bit audio files with exceptional quality.
