The UM 900 is the first switchable pattern, valve condenser microphone which can be connected to industry standard 48 volt phantom powering using a normal 3-pin XLR microphone cable.
Well I am at Armando's studio Cosmos in Mexico and about to try his best 48, 67, vintage 87, 251 and Gefell UM900. I will report back. This should answer a lot of questions. p.s. This experience of being out here is beyond words.
...have the technology to do superb nickel diaphragms and could use the same small valve that they use for the UM 900 - but is there the demand for this ?
