Musical Fidelity MX-DAC - DSD DAC

Musical Fidelity was, pretty well, the first hi-fi company in the world to make a DAC.  Since that time we had been at the forefront of DAC performance technology.  All our DACs have offered cutting edge performance, fair pricing and outstanding build quality.

Until now we have chosen not get involved with the DSD format because the technology was very fluid.

After many years of patient research and development we are proud to launch our MX-DAC with DSD.

The MX DAC represents truly outstanding value for money.  Its combination of superlative technical performance, technical innovation, build quality and value should prove a compelling  proposition for music lovers.

The new MX DAC is a tremendous performer.  It has ultra low distortion, very wide bandwidth and low noise. The technical performance of the MX-DAC is on a par with any other DAC at any price. 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.

These technical figures are state-of-the-art. They demonstrate that our implementation is almost perfect. This ensures completely neutral and accurate digital-to-analog conversion of any digital input

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. 

Even more importantly all inputs whether from optical, COAX or USB are processed in the DSD domain.  This desirable feature gives a warmth and humanity to the sound that simple digital conversion doesn’t achieve.

The MX DAC has both single ended and balanced outputs.

The new MX range has beautiful aesthetics and wonderful build quality.  The front panel and housing are both from exclusive custom made extrusions using Mil-spec aluminium.

Great DAC
16 March 2022  | 

Purchased a few months ago on AS's advice (thanks Martin). Very impressed, as not only does the DAC give music a refined analogue sound that's on a par with my RP3 TT, it also gives depth to an extent I've not experience before. Ironically I bought it to enhance my Node 2i's sound and it does such a good job that I hardly use the Node now. Such is life!

Persistence Pays
14 February 2022  | 

I was initially underwhelmed with the sound quality. I have been using the optical output from my TV into the DAC to improve upon the mediocre analogue one. It did sound slightly better, but after a number of days I was starting to hear a distinct improvement. I realised that it should not be judged on first impressions and needed time to ‘burn in’. It continues to sound better, like a rose bud gradually opening to reveal its full glory. On a well recorded high definition TV program, the sound is stunning. Crystal clear highs, excellent mid-range, sumptuous tight bass with no noticeable colouration, and a natural sound. I think this DAC is superb value for money at this price point, and wholeheartedly recommend it.

Sounds Great!
12 November 2021  | 

I was looking for a DAC for streaming and I've liked MF for years. Got to say i'm not disappointed. Build quality is still there and it's got a great sound. "Organic" as the description says.

My 1990s Marantz CD player has been given a new lease of life, Amazon UHD sounds great and my music collection has increased by a few million tunes!

Still nothing beats a turntable with an album recorded in analogue, but highly recommended nonetheless!

MX Dac is outstanding value for money, open detailed sound, but very musical. Compared to popular V90 model, this one is in another league.
