It has been a long time since I heard the PS Audio combo, so take this with a little grain of salt. I own an XDS1 which I just upgraded to v.3 status, and before that I had a CDSD/DCC2 combination. While I liked the PS Audio combination (particularly vs. most other non-DSD players I'd heard), I liked the EMM Labs house sound better--it seemed just a little more real, dynamic and extended at the frequency extremes to me. Cost a lot more, though, even used. I can say that the upgrade to v.3 is a real eye-opener, it seems to have a great increase in information retrieval while at the same time making the music more involving, a tricky balance that they seem to have done just right (IMHO).
