This is my stereo set up,H/K 3370 receiver Yamaha CDC 795 cd player,Axiom M-3TIs and aInfinity BU-80 sub.I listen to mostly soft jazz and I'm very pleased with what I'm hearing.I'ts amazing the how pure the music is coming from these small speakers. How much better can it get for the $1000 I spent? You guys are always saying how good the Denon receivers are.Would a denon DRA 395 or a DRA 685 improve my set up that much?
