Just looking for Advice on what 5.2 Channel Receiver to get. Budget is set at $500 for the Receiver so it is Tight. I want a bare bones simple to use Receiver that puts out eh most power for under $500. I don't have to have Bluetooth, Dolby, Wi-Fi, App to Control it etc. Just a Simple but Powerful Receiver that has Decent Sound Clarity & Powerful Enough to Push Speakers like Klipsch R-620F?
