I need a new AVR my Onkyo (TX-SR706) died on me and I need a new one. I am up for any brand and would like to stay under 600 dollars if possible. I have a Panasonic 58" Plasma television(TH-58pz800u) with polk audio speakers and sub running a 5.1 (RM6750) setup right now. I really have no preferences where to start and figured someone on her could give me a better idea. I do like the iphone airplay feature and the pandora capabilities but it is not 100% necessary. I did not like the sound quality from my old Onkyo but it did suffice. It could be my speakers too but Ill take all the advice that I can get. also I use a ps3 for blueray play back. Thanks for the advice in advance.
