The FMJ A32 won't be able to drive the SF GP Homes efficiently. The A32 is very similiar to the earlier model Alpha 10 which I have owned earlier but with a cosmetic makeover which explains the derivation of the FMJ tag(Full Metal Jacket). The Krell KAV-300il will be able to do a better job driving the GP's. As the previous poster has pointed out, 2 very different sonic signatures. The smooth and laidback character of the Arcam vs the grunt and dynamics of the Krell. The choice is dependent on your musical preference but given your speakers, I would definitely go with the Krell.
