Glad to hear you have your settings corrected and it helped your situation. Just out of curiosity what is your main music transport, CD or ripped music? The restorer function should only be used with ripped music as you have found out thanks to Cam's link.

Just goes to show how critical the avr settings are and how, when set incorrectly, can screw things up and the amp gets blamed.
