How is the +5dB gain increase produced inside the Schoeps CMC5 body?
With transistors.
Literally, there is a small amount of voltage gain and a massive amount
of current gain from the front end FET.
The output stage is just dual cathode followers, producing only current
gain with no voltage gain.

( Scott mean to say " emitter followers", not cathode )
The current gain is enormous throughout the thing... input Z is several
megohms and output Z is tens of ohms. The voltage gain is minimal.
** The front end FET stage would have an input resistance about 1 Gigaohm - hence the warnings about handling that area.
