Maybe it is a placebo effect. Remember that probably thousands have claimed big improvements with power cables, speaker cables, amps, etc. Of course they are always called liars if no measurements are shown.
Quite a few folks have posted measurements of their setups before and after Audyssey calibration and in most rooms, the difference is significant.
In my own system, XT32 has smoothed the in-room response significantly.
The problem is many folks who've never used room correction or measured their system's in-room response don't know how bad their in-room response really is, and even more have gotten used to the peaks in their rooms and find any smoothing of these peaks dissatisfactory.
Keith has mentioned that professional purpose built audio mixing rooms designed specifically for audio still need extensive room treatment, but what I didn't see him mention was that FilmMixer has clarified that even with rooms designed from the ground up with ideal dimensions AND room treatment, ALL these mixing rooms STILL need (and use) room correction to reproduce ideal audio.
With my previous music setup, I measured both the unEQ'd setup and the EQ'ed system and while I can see why some folks might prefer the unEQ'd sound in my previous setup (it follows the Harman preferred response, i.e a downward slope as frequency increases), I prefer the XT32 EQ'ed sound because the FR is smoother (the default Audyssey curve is horizontal as opposed to the downward slope of the Harman curve, but DEQ compensates for that).
