Strässer is a very long-time provider of complete P.A. installations for churches, public assembly halls, municipal buildings, etc. in Germany (
www.straesser.de). I don't think that Schoeps sells microphones to them any more, but they did so for decades, and nearly all such microphones have been, logically enough, speech cardioids. Their capsules can't be converted to standard (general-purpose) cardioids, and standard cardioid capsules are no longer available for the older microphone series, so this is not a way to get the sound you want at a bargain price.
Some of the Schoeps microphones that Schoeps made for Strässer which may be said to be "compatible with" 48-Volt phantom powering, may be the model CM 90--a type of Colette-series microphone designed for 24-Volt phantom powering. You could put any Colette capsule you want onto such an amplifier, but it would require (and would attempt to draw) something like 7 mA from a 48-Volt supply (sorry, I can't find the exact number). That's more than many/most portable supplies have available, particularly when powering a pair of microphones. I suspect that the factory could set the output circuit for 12- or 48-Volt operation and sell you a new sleeve and ID ring, though, and then it would be just like a CMC 3-- or CMC 5-- amplifier.
