I have opened a Schoeps KCY before and it has a board and a single WIMA Capacitor is soldered onto the board.
If I can find the pics I took I will post them
The box that Schoeps uses is VERY different to the VARK box. Schoeps uses a custom all schoeps grey plastic (lined with EMI protective paint) you can't go to mouser or digikey and order it. It is much smaller than the VARK box.
IMO there is no comparison in build quality to the VARK box - The Schoeps box is far superior.
