Musical Fidelity M3x DAC

Our M3x DAC is our new entry in affordable high-end DACs. With its technical prowess, superb technical performance, careful PCB design in Musical Fidelity tradition, meticulous power supply layout and excellent build quality, the new M3x DAC offers a truly outstanding offering modern high-end DAC design.

The M3x DAC employs an upsampling DAC design with the SRC4392, a high-end sample rate converter from Burr Brown, tasked to re-clock all PCM signals and convert them into 24 bits and 192 kHz. Up-sampling done in this sophisticated and clean implementation allows us to reach the lowest distortion levels and maintain and elevate your digital music playback.

The PCM1795 DAC handles PCM rates of up to 24 bits and 192kHz and native and DoP DSD of up to DSD256. DSD files are not up-sampled, but played in their original format.

The single ended RCA and balanced XLR outputs each have their own output buffer.

Both output stages deliver superior audio quality, exhibit very low noise, large output voltage swing and high current drive. The excellent gain bandwidth and very fast slew rate produce exceptionally low distortion.
