I think the speakers you have selected will be easily driven by any of those AVR's. If you look around, you can usualy get the Denon's cheaper than MSRP. When I bought my 2805 it listed for $900, but I waited until American Electronics had a weekend employee cost sale. I picked it up for around $740.
