I bought a Denon 2112CI a few months ago and it's made my Axioms sound better than ever. This model Denon has the Audyssey MultiEQ XT which will optimize your speakers to your room better than the 1912 which has the lesser Audyssey MultiEQ.

I got the 2112CI for $439 (list $649) shipped from ElectronicsExpo. If you're interested, I read that if you call them they may still be honoring that price. And they're an authorized online dealer; in case something goes wrong Denon will honor the warranty.
