Mic #3 Answer
Mic #3 is a TransformerLess Microphone: the Neumann TLM-170 R. There is a lot to like about this microphone, notably: a wide selection of polar patterns, nearly flat frequency response through all of the patterns, and a max dB SPL of 154 (padded). Ron Streicher and others especially like the TLM-170 to record choir.
