Yes, you are right and my wording was sloppy - but it is academic distinction. Unless you buy a NAD you won’t be able to have hi-rez and Audyssey at the same time.
I personally think dealer auditions are a total waste of time. They have different rooms, different speakers and invariably no way to conduct a meaningful test (ie, blind, level matched to +/- 0.5dB, with instantaneous source switching under the control of the listener etc). Whatever you hear in the dealer facility, one thing is 100% guaranteed: you will hear something entirely different at home.
Very true Keith and honestly when I do go I try and tune the dealer out as much as possible. I hate getting steered towards one piece of gear when I've researched the heck out of the piece I went to look at originally. IMO dealers can be some of the biggest fanboys of a brand, and I'm assuming many are profit margin driven.
