I had the 3312 before getting the 4520 and the improvement was huge. I didn't expect there to be that much of a difference. In fact at reference volumes with my Klipsch RF7II's its crystal clear. With the 3312 it started getting sloppy when pushed and I'm sure that's because of the more go go juice the 4520 has and the fact its able to handle the impedance dips of the 7II's. XT32 is night and day better compared to the Audyssey XT. I'm really enjoying this AVR. No complaints so far and really don't feel I need an external amp anymore.
