I am saying I would not base my decision to buy a processor on what version of Audyssey it has. Although almost any room can use some correction I would rather do it physically in the room than metaphysically in the processor. Audyssey XT versus XT32 isn't that big of an improvement over a room that has been adjusted to start with. If your HT is in a room which can't be adjusted physically, I don't believe any room correction can fully compensate the room. My main listening area in my Florida home is open to a space which contains about 12000 ft3 and has been adjusted pretty well by Audyssey XT on my Onkyo. It is nowhere near perfect but XT32 wouldn't do any better. My HT room in my other home is much better suited for HT and will need much less correction when it is done.
