Default Mic preamp comparison

That's the easy part. Where condenser mics differ in their sound when
connected to different preamps is whether there's an output transformer
or not, and if there is, it has a sound and that sound can be different
for preamps with different input impedance, and whether the preamp has
an input transformer or is transformerless, and the circuit topology of
a transformerless output (mic) or input (preamp.

There are so many ways to affect the sound between the diaphragm and a
usable output voltage (or digital output if the preamp includes it - a
whole other potential can of worms.
