I've auditioned Sonus Faber in a shop that used a MC275 for the power plant and it sounded REAL NICE. I auditioned the Cremona Auditor, but think the SF Olympica I would be a nice step up from the 805Ds.
FWIW I just sold my 805Ds, which had been in a Linn System. I upgraded from the B&Ws to Harbeths. I then sold the 805Ds because the Ayre Ax-7e in my media room second system didn't provide enough power. Essentially, decided to keep the Ayre & sell the 805Ds. I'm currently running the Ayre with some profoundly inexpensive Pioneer SP-BS41LRs as I plan my next move.
I don't recommend Harbeths with your Mcintosh MC275, but the Sonus Fabers might be a good way to go.
