Hello I will throw my thoughts into the pie, your thread is a good one as both preamps are in the same price range.
as far as Mac goes I own both the C2200 and the C46, also have the 252 amp and the 2751v....I have heard in my house the new C1000 (ss version) the C41. I have not heard the Calypso, but what I find is when you jump into the Mac pond it is all quite good, their gear is more similar than different, there are differences in the C46 and the C2200, to me I like them both it just depends on my mood....I use mostly the tube/tube combo and the ss/ss combo although I have mixed and matched...for instance a really nice combo on my Khorns is the c2200 and the 252. I also have small B&Ws and the tube gear really does well on them. This is probably no help, but to me I enjoy the different combos very much, it would be nice if anybody has heard the C2200 with the Calypso though.
I agree that a used C42 would be a very good value
