Hi Gang,
I was at the Earthworks factory here in New Hampshire today and I walked out with a pair of the new QTC30 microphones.

These are very small diaphragm omnidirectional microphones with outstandningly flat response. The QTC30 is 5 dB quieter than the M30 or TC30k and has a 30kHz BW (+/- 1dB) vs. the 40kHz BW of the flagship QTC1 mics.
