Musical Fidelity M6 DAC

Here on offer is our ex-display unit in perfect condition, boxed with warranty - black finish.

The design brief given to Musical Fidelity’s product development team was a simple one………… design an all new reference DAC that would complement our ‘full size’ M series product ranges. Building on our reputation of class leading products such as the M1 DAC, the team has delivered the stunning M6 DAC (pictures attached).

Dual differential Delta-Sigma 8x over-sampling 24-Bit/192kHz DAC
2 x COAX inputs (up to 24bit/192kHz, galvanically isolated)
1 x AES/EBU balanced input (up to 24bit/192kHz, galvanically isolated)
1 x USB input (up to 24bit/192kHz, asynchronous and galvanically isolated)
1 x Optical input (up to 24bit/96kHz)
1 x Bluetooth V 2.1 apt-x receiver (up to 24bit/48 kHz)

The M6 DAC has single ended and balanced audio outputs as well as digital outputs (COAX, optical and AES/EBU).

 All input level sensitivities are individually programmable (for perfect gain matching from different sources) fully adjustable from the M6 DAC remote control.

We believe that a DAC’s sound quality is closely related to its technical performance.  The more data retrieved the better.  

All our measurements are made on a Rhode and Schwarz UPV.  The THD is very low.  At 10kHz it is less than 0.0012%.  At 50kHz it is 0.001%.  These are outstanding measurements by any standard. Linearity is ± 0.3dB down to -120dB.  The signal to noise ratio is also outstanding at - 120dB.

The M6 DAC has a dual mono-bloc configuration.  There is a separate dual differential DAC for each channel.  The selected sample rate converters re-clock all data and are, in themselves, asynchronous. All inputs therefore are asynchronously re-clocked and up-sampled to 24bit/192kHz.

The power supply is ultra-low noise and encapsulated for maximum isolation.  In addition, the M6 DAC has choke regulated smoothing and 32 polypropylene capacitors for perfect decoupling and isolation.

Bluetooth (apt-x)
An increasing number of music lovers are storing their music on phones and other portable devices such as tablets. The M6 DAC has a very high quality Bluetooth apt-x receiver.  We have designed this module to have its own separate power supply.  Interestingly, we take the I2 S from the module straight to the sample rate converters. We believe this to be unique! The combination of apt-x and our coupling system yields unexpectedly high audio quality from the much maligned (but incredibly convenient and even more universal) Bluetooth system.  Also there is something magical about transmitting music from your phone/tablet/laptop straight to your hi-fi system.  It’s fun!
