Bought Zero DAC with Moon HDAM and spare parts/opamps from sandchak.
In spite of difficulties due to his location - relations with Georgia (not one in USA, indeed) and Russia are strained to put it very mildly - got it right before New Year as I was hoping, and the communication was very pleasant indeed.
Condition of item is flawless and it sounds fantastic, definetely better then my Dr. DAC2. Too bad you cannot fit HDAM into the latter

.
Btw, Happy New Year sandchak and everyone!
