This listing is for a VERY NICE Musical Fidelity M1 DAC.It has been my "go-to" DAC for a number of years. My 2 channel systems now all have High-End CD/SACD players (from Macintosh , Marantz and Esoteric) that feature built -in DACS making this fine DA Converter available. It is in perfect working order and in terrific cosmetic shape. If you look very closely you may see 1 or 2 extremely small marks or scratches. I have conservatively rated it an 8/10. Sam Telling raved about this DAC in his Stereophile Review.It was a "Recommended Component" for several years. See exerpts below: 
"The M1 DAC is by Musical Fidelity. At $699, it's a stunning bargain"
"With the M1 DAC, I heard a degree of low-level resolution I'd never before heard from a DAC. I think this may have had to do with the M1's astonishingly low noise floor"
"the M1 DAC seemed to elevate "Red Book" CD sound to near parity with SACD. Or maybe better"
 Summing Up
"What I mainly heard from the M1 DAC was nothing: an absence of artifacts, if you want to get fancy. There was no fudging of detail, no smearing of transients. Purity of tone was exceptional"
We will ship (in original box with power cable and owner's manual), anywhere within the continental USA, via FEDEX Ground/Home Delivery for actual insured cost. Reasonable offers will be considered. Local pick-up is welcome. 

NOTE: I will not be able to ship between 9/24 and 9/27 2018. If item is purchased (and paid for) before noon on the 23rd I will take to FEDEX office that day and it will go out on the 24th.
 

M1 DAC - Overview (From Musical Fidelity Website)

We've been making top-performance digital-to-analogue converters since the early days of CD. That means the M1 DAC benefits from almost 25 years of continual development, drawing on successive acclaimed DAC designs.

Whatever your digital source – from CD to computer to TV set-top box or DVD/Blu-ray player – the M1 DAC can upsample and convert it, producing stunning 24bit/192kHz resolution audio. In comparison, CD resolution is a mere 16bit/44.1kHz.

The M1 DAC features four digital inputs: balanced, USB, optical and coaxial. It is an asynchronous design with awesome performance: from its low-distortion, noise levels and jitter-minimising technology to its high-quality power supply, the M1 DAC surpasses the standards of DACs costing many times its price.

The M1 DAC has been met with incredible acclaim. Stereophile's review said it "offers performance that is close to the state of the art", calling it "a piece of kit that can transform your system " and "a stunning bargain".

Meanwhile, the review from computer-audio specialist, AudioStream described the M1 DAC as "a wonderfully musical-sounding DAC, and one that offered many hours of pure enjoyment."
