Hey, somebody had to represent Yamaha in here. I've been using a RXV1400 in a 7.1 setup with M60s, VP150, QS8s and M2s, and an SVS sub.
Extremely pleased, though I think the speakers are key contributors to the nicely balanced sound I've been enjoying. I use the space for primarily HT viewing but also SACD and DVDA surround listening. Great soundstage, extremely detailed, smooth midrange and nice blending into the lows from from the SVS. Plays LOUD enough if asked to drive any sane person out of the room without distortion.
I've had a mix of amps/receivers before, and I have absolutely no complaints with this Yamaha - it's a good piece.
