Integrated amps with room correction...

Not trying to dissuade the OP, but are you sure you need DSP? I spent a lot of time setting up and listening to a few pricey software DSP systems in my system thinking my sound would be improved. After a couple years of using DSP, one day I "accidently" listened without DSP and thought it was much more natural and enjoyable, warts and all, and haven't gone back.
