I tried the power cord on amplifier, it works fine. And Yes, I did demo it, momentarily though, I though I saw the display and heard the sound. I took so much care in bringing it home, it would not have shaken a bit. So do you think it could be a problem with D2? what could have gone wrong? Am I missing to do something, I have the ARC anything to be done in that front? Sorry about too many questions, I'm bit upset I think, I waited for long to get this set-up
