007, To me the HK 330 sounds great, and as a matter of fact I'm using the RSX-5's as rear surrounds and although I have to turn them way down, I think it is a good setup. They actually totally overpower my current floorstanding speakers which are not Klipsch. By the way, find a good price because the HK330 can be had on the cheap, got mine for around $450 when it came out, Im sure you can find it for $400 or better.
