There is this amazingly good audio isolation transformer at Radio Shack.

Can you be a bit more specific? I found a two-channel "Ground Loop
Isolator," #270-054. Is that what you're talking about? I didn't find
much else in the way of aurio isolation transformers there. From one
of the reviews, it sounds like the frequency response may not be all
that good; there are no specs on the web site (that I could find) that
tell us what the response or distortion is.
