pwaynes, Lots of good suggestions above. Couldn't help but notice you said "everything is plugged into a power wedge 116". I also have a Rev. B DNA-1 and plugging it into a PLC limits what the amp can do. Same goes for the stock power cord.
Try plugging the McCormack directly into the wall. You may be surprised at how much this can open the sound. Also, if you have access to one try a larger gauge power cord. The stock one is not too bad, but it did seem to limit things a bit in my system. Even a DIY PC will be better than the stock one. Together these two changes noticeably "relaxed" the overall sound and made things more musical and dynamic (less electronic).
FWIW, my PLC is a Vans Evers Clean Line and the PC on the amp is a Synergistic Master Coupler.
