That higher input impedence is a real plus. The Pass designs tend to be low enough in this area to cause potential mismatches with some tube preamps.
Pass Aleph vs. McCormack: What to Expect?
I currently own a Pass Aleph 3, which I like alot! It is detailed but not brash, and somewhat liquid in sound. I am missing some bass response though. I'm thinking of a McCormack DNA 125, or perhaps another Aleph 3 to bi-amp. Has anyone compared these two amps to shed light on this decision? Will the bi-amping help improve bass response? Thanks.
