The 44.1k vs 48k issue seems to be triggered by Skype on my PC. Gotta resample those ring tones...
There is no such thing as a black Musiland MD 10. Well, if you have a contact in China you could ask that person to call the factory and ask for a custom version, and deliver it to that person, who then would forward it to you. They sell ex-factory but only send to mainland China. But not sure if they would do a custom version. Any news on the supposedly upcoming MD-30?
Sound-wise, the break-in is not yet complete but it is definitely required. First it sounded hard and a little metalic in the highs (but not harsh or grainy), then it went to muddy, then the mids and highs cleared up and the bass was overblown, now the hardness is gone and definition is satisactory but still needs more break in. But I have to share the feeling that a great resolution is not a main characteristic of this Dac, mp3's sound too good, so to speak. But the desired amount of resolution is a matter of personal preference.
