I just got my NAD T747 last Thursday. Very impressed with it so far, though I don't have much experience with higher end receivers (just Pioneer and Sony low end). Have demoed mid range/high end Denons and Onkyo receivers at Fry's selecting the exact same speaker models I have in my 5.1 system though (All Polk Audio; RTi-A5 fronts, CSi-A4 center, FXi-A6 surrounds, and PSW PRO 500 sub.) First thing I did after getting the speakers connected (added banana connects to receiver side of wiring) and settings configured was play the intro chase sequence and song of "Quantam of Solace" in DTS.
Center channel had really good volume level (all speakers at deafult 0 dB gain level settings in receiver), there were sounds I hadn't heard before, and man the bass to midrange response on the gunshots was definately more punchy and very lifelike.
Even with a 60 WATT/channel rating there is plenty of power to make you go deaf quick...along with having your chest massaged by the bass at high levels. I'll take NAD's "60 WPC" over others 100+WPC.... Music sounds really good at 0 dB reference level with hearing protection on...

But even at a subdued -40 dB level music is incredible, the entire frequency range is crystal clear with bass extremely well defined in Stereo mode.
The function menu is done via on screen display which works great, but would be nice if the front display could be used for displaying and configuring settings as well, I hate to turn on the projector just to mess with audio settings.
