I have an Pass Aleph 3 also and found a very good after market power cord makes a big improvement in bass. I am using a NBS Monitor power cord with great results. Believe it or not, putting the amp up on 3 brass spikes also helped.
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.
