High-end audio outlets ... I wouldn't have believed it. I used to have a link for ungodly expensive speaker wire elevators (ceramic stands to keep your wire off of the floor) that I used for posts because I found them hilarious; but sockets might be even better.

So the recommended approach is to do nothing unless there's a known problem. Doing nothing happens to fall into my wheelhouse, so I'm all set. (I did add a surge protector.) Thanks for the advice and the laugh!
