M2Tech - hiFace

A Hi-End S/PDIF Output Interface

hiFace USB interface has been conceived to obtain the highest quality digital audio signal using a PC or MAC. hiFace input format is a data stream signal with sampling frequency/resolution up to 192kHz/24bits, available from a PC or MAC 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 and proprietary drivers allow for playing 192kHz/24bits audio files that feature the best signal quality.

M2Tech - hiFace EVO

An EVOlution of hiFace

hiFace Evo by M2Tech is the new statement in high quality computer audio interfaces. Hosted in a compact and stylish aluminium 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).
