Well it certainly looks as if you have your amp section sorted out eh? I've never owned one of their processors myself, but I do own an Emotiva amp and can vouch for the fact that they pack a lot in for the price, so you might check them out.

Other than them I've never really looked into pre/pro's, so that's the only direction I can point you in. Good luck!
