most expensive model in its RX-V series of A/V receivers (AVRs). RX-V571 at $499, 5.1-channel RX-V471 at $379, and 5.1-channel RX-V371 at $249.
The Yamaha RX-V2500 receiver is, quite possibly, the most amazing receiver you will find for just over $1000. With a fairly accurate YPAO system and room corrective EQ that doesn't sound half bad.
