The thing is, our ears can only tell us that something is wrong if we
know what it's supposed to sound like in the first place. When I see
people posting opinions of certain microphones, I sometimes wonder if
they've ever checked the phantom powering, the impedance and overload
point of the preamp or mixer input that they based their opinion on.
The thing that gets me is when someone says "the preamp has very
little headroom." You can make as much headroom as you want by
switching in the pad on the mic if there is one, switching in the pad
on the preamp if there is one, (usually) turning down the preamp gain,
or putting a pad in line between the mic and the preamp.
What they usually mean is that with the gain set up fairly high so
they can tell how "sensitive" the mic is, when someone screams into
the mic, the preamp clips. One of the things that makes a mic preamp
design less than trivial is that it needs to be able to deal
comfortably with a wide dynamic range, but there's a maximum output
voltage for any circuit. If you put a sensitive mic in front of a
loud source and follow it with a lot of gain, you'll exceed the limit.
