I agree with Sdcampbell and Onhwy61. The speaker room interface is of paramount importance, and optimizing it will likely yield greater significant sonic improvements than any kind of component upgrade would. You already have a very nice system.
I've also become a big believer in a high quality dedicated AC system to include excellent receptacles and good power cords that suit your taste. Good Luck, and Cheers. Craig.
