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
