Synergistic Research Tesla series would be a great start. Borrow them from the Cable Company (they're on-line and a great resource)
Teslas work phenomenally with my MC225s.
Check out the Tesla Power Cords... T2 for your preamp, and T3 for your digital source... you will be very surprised and glad you did.
The Tesla SCs are great. Call Ted Denny at SR and tell him the equipment you have, borrow the cables from the Cable Company, and consider the results.
Happy listening!
