They are a great combo. Both pieces are fantastic but I would suggest you get the C46 instead so you can do some room correction - that will make a huge difference. They will be a better match with Wilsons than SFs IMO.
After exhaustive research,listening etc., It became clear to me that the MC352 is a much better amp than the 252.
I just purchased one new from Audio Classics.I believe they are the only ones that still have access tha these from McIntosh.The MC352 is for essentially a MC402 with a flt faceplate ,different speaker terminals and bulbs for meter illumination instead of fiber optics.BTW I have a C2200. Great Combo!
