Re: a partial soundfield stereo mic for studio.
lol you are asking a lot of what I asked when he braided to redo this. The 165¡¯s are great but the 2555B is better imo. But fitting three in a donor body is a challenge. Ideally I want to do two or

Re: DIY mic activator body options?
I¡¯m experimenting with some dynamic mics as budget indoor boom mics for interviews. Typically, the mic for this application would be a hypercardioid/supercardioid SDC with 20-25 mV/Pa sensitivity,

Re: chOPA EM700 (op amp based charge amplifier preamp)
I'm not sure you can make this claim.? I have a somewhat more complex analysis of mike noise in Zephyr.doc ( /g/MicBuilders/files/Mic%20Measurements/Zephyr.doc )

I'm quite the opposite... I managed to squeeze 14 bipolar transistors (packaged in matched pairs), 21 resistors and 5 capacitors into a FetHead-style body. It's a true fully differential amplifier
