Yeah, same point though - the KC contains an FET impedance converter; I gather the CMR acts as a preamp as well.
(I guess I didn't spot the KC ends in the pic of the Rbox.)
Anyway, it's a moot point, as there's no way I can afford Schoeps, and already have a nice collection of AKGs. Just trying to figure a way to do a similar thing with my CK61/62 caps...
