What you get from a power line or a wall wart is interference from

Picky, picky.
A friend of mine with this problem actually got Verizon to turn off the
transmitter on the tower that was causing the interference with his
mics, but it took a lot of complaining. Something that might help (he
got the transmitter turned off before he placed the order) is to change
out the connectors on a few mic cables with the Neutric EMI-filtered ones.

These connectors appear to be a good idea for high-frequency
interference. It would be interesting to try them. If I were on the road
a lot, I'd probably use cables with them all the time.
