I've narrowed down my choices between the exact amps the OP was looking at, the Yammy RX-A820 and Marantz SR-5007. Looking at the spec sheets and reading through the manuals they both have all the important features and settings that I either lack or don't like on my current SR7002.
Of course what I don't know is how they sound, or how they are to use everyday. It only has to power the rear three channels, fronts are powered by Parasound, so amplifier section isn't important, pre-amp quality is. Ergonomics are second. Almost nothing else matters.
Music quality is tantamount to movie sound. I've tried a few receivers and all are very close for movies, but seem to vary quite a bit for critical 2ch listening. (Though if money was no issue I'd have a separate 2ch rig )
So, what say the Polkies?
