I own a Yamaha RX-V3800. It's a great matchup to the KEF 6000ACE System w/ PSW-2500 Sub, and a Pioneer Elite 50"
Great Receiver. Then again, you really can't go wrong with a Yamaha. Their Video Switching, Amp sections, and Extra Zone capability (especially) are hard to beat as a package.
But, I really like the new Adaptive DRC and DSP. No AV Receiver should be without it. True real world listening technology.
