1. Since electrets have a fixed charge and don't take a charge to the capsule, is it correct that pretty much any electret capsule can work with any other electret microphone preamplifier, and if not, what are the parameters?
2. How long can the leads between the preamplifier and the capsule be, in practice, if shielded, without significant degradation of the signal?
2a. Is the "self-noise" spec really attributable to the capsule and not the preamplifier? I have seen cases of a capsule sold individually with a much higher noise spec stated than the commercially available mic using that capsule (e.g. TSB-2555B in the CAD e100s.).
