I agree with you on this one Jerry. I can't see anything in Pro that will satisfy tvrgeek. I think his best route to audio heaven would be PEQ and REW. This would give him the manual control which is so important to him.
Hey, that's fine guys, there's certainly validity to that.
But the OP asked if Audyssey or Marantz was the problem. Well, my way of looking at it is that it's kinda both-he needs a better processor-one with more capable Audyssey processing, i. e., XT32. And if he wants tweaking capability and the best SQ Audyssey has to offer, then he should get a Pro-capable processor and Pro kit. Frankly I don't think he should waste his time with XT and apparently he'd reached that conclusion himself.
If the OP expresses further interest, we can continue...
