I'm running my now "ancient" C2200 with a 302 and could not be happier. If you like the look of the 47 go with that. I had one in-house for a tryout and thought it was a great unit. I like the 52 better due to the EQ flexibility. But if you don't use tone controls and won't miss the meters than it's a wash. Plus you'll save some decent bucks! In either case check with Audio Classics for a B1 "used" one. B1 means it's basically brand new and you save even more that way. As for the 52 being overkill. Um, no. And you might find the stellar EQ system bests your current BSR. Just my 2c's, YMMV.
