i concur fully with the two respondents so far.
i owned CSBs for a couple of years & made some great recordings with them -- seriously! bought CSCs because i figured cutting the chatter from the rear would improve my masters. they did not, not at all.
if you'd like to do a little comparison shopping, i did a three night run of sonic youth at irving plaza back in june of 1998.
night one: csb > d8
night two: dsm6 > d8
night three: csc > d8
i stood in the exact same location for all three nights, and the CSC tape is easily my least favorite. but, truth be told, none of these tapes get any spin time now, having been passed over by the schoeps masters, the boards, et al. (not to mention the fact that kim gordon's tunes from that era annoy the living bejesus out of me)
if you've got the money, buy a pair of 4061s. they smoke ALL of the other (relatively) low-cost options IMHO.
