HELP Why no bass? Why bright?


I recently purchased a new Arcam FMJ A22 integrated and the matching power amp (P25) and am struck by the lack of bass. By comparison, my Arcam DIVA A65 integrated was very warm sounding. Is it the amps, interconnects (Transparent Music Wave) speaker cables (DH Labs silversonic Q14 bi-wire) or the B&W CM2 and B&W CDM7 NT speakers? Do the amps need to break in? Could it be that the bass not lacking, but much more controlled?

HELP!!!

one last thing, if you do move to the wharfedale keep your DH labs silver cables, a bright cable will be a good fit with a laid back speaker like these.
Before you toss the B&W try hooking them up to a Classe CAP 101 or 151 integrated. I heard this very setup and there was plenty of bass but can't remember if it was too bright. Didn't seem that way to me at the time.
Read some reviews on Classe int. and I think you'll find they are voiced somewhat "dark" and with plenty of bass.
Is it possible to address this issue without knowing room dimensions, speaker placment, and listening position?
