This whole business of low noise microphones and preamps is in my
experience a non-issue in the vast majority of cases. Very few
environments are quiet enough to be softer than the noise level of
most microphones. This is true in most cases of recording nature
sounds and very few recording studios get down below NC 20. Concert
halls are even noisier, and we rarely make recordings in anechoic
chambers, however isolated they may be.
Sampo is right about the ease with which a high quality mic amp can
be put together, taking reasonable (and obvious) precaution with
screening, rf suppression and PSU smoothing. I made a simple
two-channel amp with two THAT1510 ICs in a small box for use with
ribbon microphones. It can be powered for hours from two PP3
batteries, and measures and sounds as well as my much more expensive
RME UFX amplifiers.
