Musical Fidelity M6S R DAC Upsampling/Reclocking DAC replaces the M6s DAC with some notable upgrades including improved USB socket, better DSD support and Roon Tested accreditation.


Like the original model, M6S R DAC also has seven inputs including three coaxial and three optical. The USB micro B input has been upgraded to a standard USB B port following requests from consumers. It has also been Roon tested and certified.

While it still accepts all data rates up to 32bit 768kHz and DSD 64/128 (DoP), the upgrade now supports native DSD 256 with ASIO Driver Playback. Highest manufacturing and qualitiy standards are achieved by fully switching the entire production to be made in the EU. Made to tighter tolerances, longevity and build quality are better than ever before.

Exceptional Performance

The M6S R DAC offers exceptional low distortion levels with and low noise floor. stereo separation is above 120dB and linearity is above 110dB. this DSD DAC truly excels in technical performance and will drive your headphones to their maximum performance potential.

Impressive Headphone Amp

Boasting a high performance headphone amp with incredibly low output impedance and single ended and balanced output stage that deliver very low distortion levels, the M6S R DAC is an impressive performer. Switch between fixed or variable mode to enjoy the benefits of the impressive circuitry and exceptional load driving characteristic.

Effortless Transparency

The M6S R DAC delivers a musical experience that is effortless in its grace and transparency. The sonic impression is hypnotic, ensuring your music is reproduced in beautiful quality. Every aspect of the sound is sweet and clear, and the treble can be enjoyed grain free and with an extended bandwidth.
