It would seem that a dynamic mic has no self-noise, is that so?
Yet to get the same gain as a condenser one has to crank the gain
up much more on the dynamic, raising the noise level. Is it ever
the case that when recording soft sounds, one could get a lower
noise recording with a dynamic? Would it take a very expensive
preamp to achieve this?

I would guess that the output level of the dynamic would be
key. Any recommendations for a high-output omni dynamic for
$100-200?
