I'm going to respectfully disagree with you there, Dave. The auto room correction and EQ systems in modern receivers are designed to do the opposite. While perhaps all modern receivers could sound the same with all processing/EQ shut off, my decision on which one to buy is driven in part by that processing and EQ. I know that I like MCACC, and while I expect to like Audyssey, I've read some posts here where people preferred to have it turned off (I think that it had to do with dialogue).
Oh, I stared at that for a bit this past weekend.

Just too pricey for me.
