Sorry, I missed that post; I do apologize for the last outburst.
I do have an interesting question for you, and I am being serious. Is the cord plugged directly from your DVD/CD player to the wall outlet, or do you have it plugged into a power bar or power conditioner/surge protector.
I am being genuinely curious. If you have it directly into the wall outlet, have you tried it in a power bar, does/did it make any difference in sound.
I truly believe that you and your friends heard a difference in sound quality; I am just trying to find out why? My engineering background forces me to trouble shoot these type of things, to help me find the answer.
Thanks
Paul
