Altec,

I also agree with what you said about proper acoustics when designing the room and, of course, that should be the most important consideration. PeterT added some "real world" scenarios to the mix and for this systems such as Audyssey and Trinnov can clearly (no pun intended) serve a purpose. I would add to this the fact that even the best of rooms sometimes have minor adjustments made after the fact (different furniture, slight change in speaker orientation, some different components, etc. not to mention speakers changing after a break-in period) and only the most ardent among us would take the time to adjust the physical acoustics of the room at that point. For MAJOR renovations - yes. But for the little stuff - probably not. A properly designed room equalization system can complement a properly designed room over the long haul for most applications.

In that respect I think we are on the same page here.
