My 10 year old Denon AVR started overheating and shutting down during the Super Bowl last night - with 40 people at my house! Luckily we got through with other TV's and numerous resets, but I'm on the hunt for a new AVR and need your help. Currently running 5.1 surround sound and I need Zone 2 capability for music on the patio. Connected are: HD cable box, wireless DVD/CD player, Apple TV. Would love Airplay to keep from having to change all the inputs I now have to with the Denon/Apple TV. My audio needs are pretty simple, but I don't want to skimp - budget of $500, slightly more if justified. I don't really understand if an AVR with 80 watts per channel is significantly less than one with 100 wpc. Saw the Yamaha RX-V675 on Amazon for $400, but that was just the first one I ran across that looked appealing. Thanks for your help!!
