i owned a pair of the schoeps cmc64s. sold em and now use DPA 4011s, 4006s, and akg c481s, all of which IMHO kick the schoeps mk4 caps around the block. OTOH, the schoeps mk41's are fantastic caps for ORTF and NOS work in live venues - pretty hard to beat with anything. in a more controlled setting (studio applications), the mk2 omni is also wonderful. the schoeps fig 8 caps (Forgot the mk #) make a near perfect blumlein pair, and ranks right up there with with anything i can think of.
