Sure. If one can assume that it lacks main-amp inputs (rare in AVRs) and an HT bypass (never saw one in an AVR), you should use a stereo analog line-level input and make sure that the gain (volume) is absolutely fixed at the same setting all the time. You should also use a 'direct' mode to make sure the NAD never does any processing of the signals.

The NAD T773 has main-in jacks so you can use it as an auxillary amplifier, just go from the pre-outs of your new preamp/processor to the main-ins of the T773 and connect your surrounds to the appropriate speaker terminals on the T773.
Forget about stereo analog line-level inputs, fixed gain and 'direct' mode.
Good news. Ignore my assumptions.

Your assumptions were pretty close. I was getting so many different answers on other forums also that I figured a call to NAD was in order.
Yes, the T773 has main in's which make it a dedicated power amp when they are used. The prepro in the T773 is now completely out of the picture. No need to worry about volumn control or any sort of processing because it's totally disconnected. Now I have one hell of a 7 channel amp waiting to be used. For now it'll power my surrounds & down the road it'll power my back surrounds & I'll still have amps left over.
