Your MC275 actually puts out closer to 90 wpc, so they should be plenty powerful enough to drive your Wilsons. If you haven't changed out the stock tubes, I would suggest getting some Gold Lion Reissue KT88s - big step up in musicality and dynamics.
I run my MC275 with a C1100 preamp, but since you do not like vinyl, I would suggest you look at the new C2600 - all of the goodness of the C2500 with an improved DAC.
I also have an MCD550 SACD player with my setup because I like the single brand look and system synergy, but you can't go wrong with the Marantz. If you want to try a Modwright, I would suggest that you try to find a used unit. I sent my OPPO 105D to them for the full Truth modification and upgraded tubes. For a variety of reasons I ended up selling it at a pretty steep loss.
Hope that helps.
