I own the PWD MKII and it is in a completely different league than the MKI. It's critical that if anyone compares this DAC with anything else that they have the 2.02 or 2.03 firmware installed. It's the most musical DAC I've ever heard, beating the Super modded Meitner BiDat as well as the latest T + A and Bel Canto gear. I know someone who's compared it extensively to the Berkeley (which it beats) but he says it doesn't quite reach the heights of the Meitner and dCs flagships. If a person buys the PWD MKI used and installs the MKII upgrade board (which you can do yourself) ..that's quite a good deal in my book.
