This is very old but I thought it was still timely given that Denon doesn't even sell pre-processors anymore. That said, it is (was) heartening that Denon offered owners the option of an update. The killer was the 1K price tag. Now the same pre-pro can be had for under 2K used. The flurry of "new" modes was too dizzying for anyone to care (really, how many people are running height channels???), while room correction was given second consideration. I would still consider getting one of these behemoths as long as it came with the upgrade so I could enjoy the XT32 rc.
