Nothing out of the ordinary , I would like , I think , to remove the kappa perfects and the dcx 2496 and of course the power source ep2500 , then replace the set up with an all in one unit from HSU/SVS for the ease of connection and so on maybe a pair of matching subs in a piano black to match my Carnegies and I may even let the Pioneer SC37 go as well and pick up a 7.2/9.2 receiver that offers a true pass thru, that issue has bothered me to no end. Maybe I am getting too picky about my HT set-up, who knows, but change is good sometimes.
