My Harmon Kardon AVR 354 just crapped out on me, and I'm looking to replace it. Just purchased a pair of RF 82's with a RC 52 centre. Anyone have suggestions for a receiver for me? I really thought my 354 was under powered for my speakers. I'm leaning towards Denon's AVR-1912 right now, as if fits my price range. Looking to spend $400-$700. My concerns with the Denon is that it doesnt upscale to 1080P, but now that my 354 is done, im running my hi def sat receiver straight to the tv, and I cant tell the difference. You guys think upscaling is worth it?
