Sorry, but there is no way that the DP-55 is better than the DP-75V. The DP-55 uses the older MMD conversion process vs. the MDS system as implemented in all of Accuphase's latest generation DAC's (including the DC-330). I suspect there was a problem with the 75V you were auditioning or some odd system synergy issue.
Accuphase 85 or 75v...or EMC-1?
I am soon to get a Pass Labs X-1 pre, and will run it single-ended, for the time being, to a Classé DR-8 amp. I need help in deciding on cdp. I know the Pass prefers balanced, but how will it interface (in the meantime) with the above? I guess I'm asking several questions, here. Are either companies' cdp's more compatible w/balanced or single-ended? Which of the Accuphase sounds better on redbook; how does the Accuphase "champ" come out against the EMC? (No, I don't care much about SACD, and don't see it being much of a force for 4 years or so; interestingly, they're much more available (at very attractive prices, too), for the time being, than the 75v...)
