Musical Fidelity - MX-DAC DSD DAC Jitter is about 12pps, s/n ratio is -116dB ('A' weighted), linearity is +0.2dB at -116dB, stereo separation is -104dB at 1kHz, frequency response is ruler flat and distortion is 0.00025% at 1kHz and 0.0003% at 20kHz. The MX DAC has both single ended and balanced outputs. The MX DAC has inputs for: 2 x optical (up to 24 bit 96 kHz), 2 x COAX (up to 24 bit 192 kHz) and USB up to 24 bit 192 kHz asynchronous. Importantly, it also has inputs for DSD 64 kHz and 128 kHz. The front panel and housing are both from exclusive custom made extrusions using Mil-spec aluminium. All inputs whether from optical, COAX or USB are processed in the DSD domain.
