I am dealing with the Technical Product Manager of the United States for NAD, based in Canada, and occasionally the National Sales Director for the United States. Yes the first and second receiver was tested with different equiptment, even totally different systems(the T752 has only been on a different system), it is not the equiptment(sound like them). Is it so hard to believe this company just sucks? Documenting is my number one priority(receipts, emails, service summaries, ect....). We'll see what they have to say about the T752. It has a 1 year warranty with it since the exchange has taken place. I honestly hope they dont have the balls to suggest I start sending this one back and forth, this is why a replacement was in order in the first place. We'll see.
I still have my Denon 3803 which I am overly please with, so its no sweat.
