Krell KAV-400xi vs. Parasound A21+P3

I've heard both setups: I used to own the parasound stack with some mission speakers, and I auditioned the krell with proacs next to the plinius 9200 the art sam2, and pathos logos. The lrell was actually quite impressive, and was def punchy in the bass, but the proacs are punchy speakers. I actually went into the listening session with anti-krell prejudice but came out liking it nearly as much as the pathos. The parasound is nice gear too, but I preferred the krell, much to my own surprise. FWIW

I would have to agree that the bass problem probably isn't the krells fault--that's one of it's strong points. I would say see if you can swap in a different pair of speakers and see how the krell sounds. Poor bass could also be a room issue: how are your speakers placed int the room and what's near them?
