So, I've been listening all day to the MyDac using an unshielded twisted pair interconnect for the digital signal from the cd player, an Audioquest Big Sur RCA to stereo 3.5mm cable into my ALO National and the Q Audio silk headphone cable into my HD-800s and even at this early stage I can say this dac is really, really nice. I did listen to the same system first direct from the CDP as a baseline and there is simply no comparison. I'm not sure what the dac chip in the Piano CDP is, but I do know that it upsamples everything to 24/192 and has sounded decent in most of the systems I've tried it in, but the MyDac takes things soooooo much further. Nicely balanced, not harsh at all, but not overly warm either; very nice soundstage (and I think you have to give credit to micromega for what appears to be a superb jitter reduction scheme as the CDP with an unshielded twisted pair is pretty much an acid test for jitter. Nicely balanced from top to bottom, very nice but not overdone dynamics -- all in all, even right out of the box this is a very impressive dac.
Can't wait to get this hooked up directly to one of the mac minis and play some high-res files through it.
Let's put it this way, if I paid $1500 for it I wouldn't be the slightest bit disappointed, so at $370, I have to think it's more or less a no brainer.
Of course things are bound to change as the National, cabling and hd-800s break-in more along with the dac, but even with nothing special in terms of cabling, power distribution, etc., this thing is performing like a champ.
