For best sound quality, the NAD and Cambridge Audio AVRs are in a class by them selves IMO. They have the lowest distortion driving actual speakers. The NAD T-758 is probably the best AVR for $1000.
Units from Yamaha, Pioneer, Anthem, Onkyo etc. are strictly second rate in their ability to drive real-world speaker systems with low distortion.
All published specs are pretty much worthless, because they test the amplifier only with a resistive load to get them This does not tell you how the amplifier will perform with the complex reactive load of a real speaker (which cheaper amplifiers can't handle very well). With any real speaker for a load, the amplifier distortion is way way higher than with only a resistive load.
Testing an amplifier only with a resistive load is like testing a group of high-performance cars only on a dynomometer, and never driving them on the road. How do you draw useful conclusions? The answer is....you don't!
That's not the real world.
