I bought a Yamaha RX-V663 from JR a couple of years ago for under $400. I am sure that you could get the current model for a compable price. Even though some would consider this entry level, it wasn't quite the cheapest in Yamaha's lineup, it decodes all the latest and I would go deaf long before the sound would be distorted due to the volume knob.
