No priest in his right mind would enter this living room knowing the circumstances right now. I'm thinking I need to throw my Denon into the mouth of an active volcano. However I want to test this unit with something else like the MP3 player or by plugging it into the back of the DVD player to see what happens before I write off the Denon. Is there a way to test the 'subwoofer pre-out' on the Denon to see if it's shooting lightning bolts or something?
