Musical Fidelity M6x DAC - Digital-Analogue Converter

The Musical Fidelity M6x DAC is a complete high-end solution, designed to convert almost any digital audio format in the highest quality. Its sophisticated DAC architecture is coupled to a class-leading analogue stage that introduces your digital music to the Musical Fidelity sound for true sonic superiority.

Super Silent Power Transformers

The M6x DAC displays our continued development of our Super Silent Power Transformers. Industrial grade power sockets with EMI filter and DC blocker stop interferences and eliminate transformer hum. The encapsulated toroidal transformer with low core saturation is ideal for audio applications and especially perfect for digital audio due to its extremely low electromagnetic radiation.

Correct PCB Design & Layout

Digital to analogue converters, compared to analogue amplifiers, present their own design challanges. They work in different domains, have their own requirements and need to be treated as such. Power requirements are unique and solutions designed for amplifiers will not show similar results when paired with digital circuitry.

The design & layout need to be custom-tailored to each application, measure well AND sound as envisioned. At this point, the listener is given a palpable sense of the recording venue that places the performers in a real-time holographic space in their own homes.

Headphone Amplifier

The built-in headphone amplifier‘s current-feedback AB architecture delivers high bandwidth, extremely low noise, and up to 128dB of dynamic range. Three key features make current-feedback amplifiers outstanding for audio. The high slew rate prevents odd order distortion anomalies. Current-on-demand at the output enables the amplifier to respond quickly and linearly; when large amounts of output power are suddenly needed, the amplifier can respond extremely quickly without raising the noise floor of the system and degrading the signal-to-noise ratio. Gain-independent frequency response allows the full bandwidth of the amplifier to be used over a wide range of volume settings.

Mechanically Sound

Paying close attention to every aspect of the M6x DAC, we get incredible technical parameters and effortless sound quality full of grace and transparency. The mechanical construction is uncompromisingly rigid and solid in typical Musical Fidality tradition. Front panel and side panels are milled from extruded aluminium profiles.

The exterior doesn’t only look clean, stunning and indestructible, it also protects the internals against outer electromagnetic fields, and in the same way, the rest of your HiFi gear against electromagnetic fields generated by the M6x DAC. Not using a big display on the front panel only increases this effect, as the cut out needed for it would drastically complicate things.
