Stunning realism from your digital music sources

When was the last time an audio component transformed the sound of your system? This one will! Simply connect Musical Fidelity's M1DAC digital-to-analog converter between your digital music source or computer and your receiver or amp, then sit back to experience a sonic thrill ride. This little beast of an outboard DAC (digital-to-analog converter) takes the place of the DAC inside your player or PC, and precisely transforms those digital zeroes and ones into rich, densely layered sound. Your music will emerge from a dead-silent background with startling realism. Instruments gain harmonic complexity and vocals spring to life with the dynamics of a live performance. In other words, this thing sounds huge. How did Musical Fidelity achieve such a feat? Good old fashioned engineering and plenty of experience.

Now with the asynchronous USB technology advantage

Standard USB outputs from most computers pose a serious limitation to sound quality. That's because while you're trying to listen to music, your PC is busy performing virus scans, data backup, and other background tasks that may take priority over your tunes, causing it to alter the data rate to suit its own needs. Unfortunately, this situation results in timing errors within the digital data stream — known as "jitter" — that adversely affect sound quality. Jitter can make your music sound harsh and edgy, and smear subtle details.

The newly re-designed M1DAC neatly solves this problem by reaching out to your computer through the USB interface, and instructing it to relinquish control of the data stream timing. In its place, the M1DAC inserts its own separate, or asynchronous, clock to precisely control the timing of the data rate, reducing jitter to the vanishing point. You'll hear a stunning improvement in low-level ambient detail along with a wider, deeper soundstage.

And for all you high-res music lovers...

Along with all the sonic benefits the M1DAC provides for your compressed and CD-quality music files, it also has another trick up its sleeve — it decodes high-resolution data streams with up to 96kHz/24-bit resolution through its USB connection, so you can enjoy better-than-CD audio quality. If you download high-res music files from HDtracks and other audiophile sources, this DAC will ensure that you hear them in all their glory.

A beefy build for better sound

Musical Fidelity was one of the first companies ever to make outboard DACs, so they know what it takes to create a great one. The M1DAC's thick, extruded aluminum faceplate and heavy-gauge steel casework provide a strong frame to help eliminate vibrations that can adversely affect sound quality. Its state-of-the-art circuit design uses top-quality components carefully laid out to maximize performance and minimize interference. A filter-choke regulated power supply on the DAC's main power input blocks out unwanted noise from the AC line. All of this goodness is contained in a beautifully built half-width component you'll be proud to display on your shelf.

Advanced circuitry ensures precise detail

The M1DAC upsamples all incoming digital audio to a 192kHz/24-bit signal to resolve extremely fine detail, even from compressed music sources. Its digital-to-analog converters are used in a dual differential configuration to cancel out noise and distortion while providing excellent stereo imaging. The end result is reduced distortion, ruler flat frequency response, an extremely low noise floor, and dramatically improved sound from every digital source in your system.


The M1DAC sports multiple inputs to handle your digital sources.

Versatile connections for your system

The M1DAC A gives you four ways to connect your digital source components to your home audio system:

  • coaxial digital input is ideal for connecting a CD or DVD player, Logitech Squeezebox™ Touch, Sonos® ZonePlayer™ 90, or any other digital audio component with coax out, and taking advantage of the M1DAC's high-performance processor for better sound.
  • optical digital is ready to take on most HDTVs, a set top box, game console, Apple TV, or other digital sources with optical digital output, and feed a high-quality audio signal into your stereo system.
  • Type B USB jack feeds the output of your computer into the M1DAC A's onboard digital-to-analog converter, bypassing your computer's sound card to yield much higher quality sound with stored music files and Internet radio.
  • balanced digital XLR input provides a pro-quality, ultra-low noise connection from a compatible high-end CD transport.

A pair of gold-plated RCA outputs lets you connect the M1DAC to your home audio system's amp or receiver. You can also feed a set of amplified speakers or headphone amp for a compact, high-end desktop stereo. Musical Fidelity includes a pair of balanced XLR outputs for an even higher-quality hookup with compatible audio components.

Turn 1s and 0s into sweet sounding music

Why buy a separate DAC? These devices are all about getting true high-fidelity sound from digital sources like computers, streaming music players, smartphones, and more. While these kinds of sources usually have their own digital-to-analog converters built in, you can expect a separate DAC to give you much better accuracy and finer detail.

Crutchfield Customer Review (What's this?)

Just when I thought it couldn't get any better, I decided to move my extensive collection to an audio server. While it sounded good, it didn't approach the reference equipment I have been using for the last several years. Only one word is necessary to describe the experience with the M1DAC-A..... WOW! I have a vintage Sony ES CD transport that actually measured better than published specs and was heavenly in performance. I thought I'd run the coaxial out into the M1DAC-A just for kicks and was pleasantly surprised with the new sound! Upsample from a near perfect 44.1 on the inboard DAC to the outboard M1DAC-A brought a 20 year old piece of equipment up to date with a musicality the exceeds all expectations. Sound stage is wider, layering nows seems limitless. Resolution and detail are now over the top. Had I known this kind of sound was possible froma computer, I'd had made the change a lot sooner!

Pros: Sound is quite warm and accurate. Setup is so easy it can be performed by a caveman LED indicators on front panel are nice to verify that the conversion is taking place at proper rate. RCA and balanced XLR outputs super convienent in mating with both consumer level and pro level components. Substantial shielding and enclosure construction is exceptional for a modern component. No plastic all metal. Helps shield against RFI. Performance is equal to more expensive DAC's currently available.

Cons: At this price point, really no cons on the M1DAC-A

Crutchfield Customer Review (What's this?)

I'm new to the world of DAC's. I've only compared this with the PeachTree DACiT. While Peachtree is okay, the difference between it and the Musical Fidelity are vast. The Musical Fidelity DAC covers the high end with pristine clarity, revealing elements to my music that I'd never heard before. The only negative I've experienced is the Musical Fidelity DAC is somewhat lacking in warmth when listening to CD quality (or below) music. However, the right computer audio player can fix this. I listen through my Mac and find the Channel D Pure Music player to be a perfect companion to the Musical Fidelity DAC.
