It's not so hard in the condenser mike world where you can design an
amplifier to go into a wide range of loads, but with a dynamic or ribbon
mike it's hard to make a mike that is immune to loading and also has a high
output level. Plenty of mikes like the SM-57 are touchy about loading,
while others like the 441 sacrifice efficiency for being able to work into
a wide range of preamps without changing response.
It's easy with a condenser mic because the first stage of the preamp
is built into the mic, so the loading is always going to be right.
You'd think so, and that's true with a well-designed condenser mike that has
a nice low output impedance. But I have seen a few condenser mikes with
transformer outputs that were touchy about loading!

Transformer - there's your problem.
