My wife couldn't bear to make me wait. I've received my unit in black and am breaking it in now.
Speakers: B&W DM 610s
Amplifier: Musical Fidelity B1
Sound files: .flac
Software: JRiver Media Player / ASIO4All
Upon opening the box, I had three thoughts:
1) The unit seems reasonably well built. The case and controls feel solid
2) It comes with a wall wart--I wonder if this results in less interference by having the power supply away from the unit or if that was a cost-cutting measure
3) I don't believe that I've ever seen such a cheap USB cable in my life.
So, I connected the unit with a better USB cable, and played the Dead Can Dance Ubiquitous Mr. Lovegrove. I was floored by the imaging and sound stage. The latter exceeded the dimensions of my listening room. Next, I played the Chemical Brothers Setting Sun. With both of these excerpts, I was very impressed with tight controlled bass.
Before listening to more demanding music, I created a play list of very eclectic music and let the DAC run for about 36 hours. I played a number of excerpts (William Grant Still's Afro-American Symphony, Messiaen's Quartet for the End of Time, CPE Bach's Symphonia, & etc.) and was disappointed in the somewhat harsh nature of the highs. The bass continued to be extraordinarily well behaved, and the mids were quite warm.
I let the unit play for another 30 hours or so, and while the highs still seem a touch harsh, they seem to be mellowing somewhat. I am hoping that trend will continue.
I'll keep you posted,
