Keith,those are pretty points however the word "easy" does NOT apply to room tx/REW, but IMO it does apply to using Pro.
I especially agree that XT32 is a great bargain, as it is "free" and available in many AVPs, some AVRs avail street well below $1K. Pro is less of a bargain as most things as we move up the audiophile chain. BTW you keep forgetting Pro is $150 license and $550 kit NIB = $700.
My experience with both XT and XT32 is that Pro better integrated the surrounds with LCR, and the mains with the sub noticeably better than the consumer version by itself. Yes, and to a stunning degree, XT32 (consumer) had the same improvement over consumer XT. But Pro-ing XT32 still brought more of the same improvement. For me, Audyssey came to my theater after I had treatments, so I never had the eureka moment from treatments.
That is my experience and I have trouble understanding how that same experience would not be shared by anyone else traveling the same path.
