thanks for the reply Hootie - I haven't had access to the NAD T773 - there's a marantz dealer and another store with the elite along with some other set-ups 1 per room, in town...
I defintiely liked the sound I heard from a 2 channel 100 W/ch Parasound amp being fed into Paradigm studio 100s... but the elite is set-up in another, lower-end room, and sounded nice if not as musically detailed as the Parasound set-up. I also heard a Rotel 1067 receiver, but it is 2250, which with tax is $1000 more than the 773.
My NAD inclusion came from the following logic:
1) If the NAD 773 is comparable in sound to the Rotel 1067 (which may be completely incorrect) then I'm all about the NAD.
2) I have heard that NAD's EARS processing is actually good unlike the "stadium; concert; etc." modes other receivers (Yammy) offer and new 773's have been updated with PLIIx - the rating of 110w is pretty on the $ to each of the 7 channels. It has 2 power supplies, and is a flagship receiver, which always seem to be made better than the other units (e.g., 59txi v. 56 txi) - I think the NAD is 53 lbs, which is quite a bit heavier than the 56txi
The Marantz I heard (playing Sting) seemed to provide uneven sound where the center speaker was very loud and the mains were way soft, which reminded me quite a bit of my old Kenwood I'm still using - but that very well could have been the set-up as the employee did not seem very knowledgable. Still, if I'm using that as the basis for how a similarly priced marantz (SR 8500) rates then I'd defintely go with the Elite. The employee also had to crank the volume knob on the marantz quite a ways to get sound from it. The sound itself was okay, but nothing to be overjoyed about.
I guess I have found out that there really are no answers, just more questions...
