Dynamic microphones: These are magnet based. They work a bit like a speaker in reverse (in fact, a speaker can operate as a microphone).
Condenser: Bigger cousin to the electret microphone. The cartridge size most effects sensitivity and noise. They often require phantom power to drive the microphone and to power a small preamplifier right at the microphone.

LT1115: low noise audio op amp with RIAA response. Bipolar, so it is not ideal to start new projects with, but it's well known.
AD743 / AD745: FET input op amp. ultralow noise.
OPA627 / OPA637; FET input ultralow noise.

Wildtronics makes parabolic dish microphones.
