Charles, the capabilities of the pro unit appear to be a significant advance over what is generally regarded as the best now available in receivers, i.e., the Audyssey MultEQ XT. The question is how much of the capability will transfer to the 972. There've been some sketchy reports that those who've heard the processor in the 972 recently have been very impressed, but these shouldn't be given too much weight, and extensive testing is needed.
