The Yamaha RX-V1065 does not count, it's still got that "I'm sold at Best Buy" feel. The RX-V1800 and RX-V3800 on the other hand, those are hefty receivers.
And as far as Denon is concerned, there's nothing wrong with their lower, middle, and upper end receivers in terms of the amp sections IMO. That said, you can't really go wrong with an upper end model.
Marantz seems to offer consistantly good models in all price ranges as well. And at A4Less they are hard to beat.
