Yes, I'm sure they do. With a SS BTL bridged power amplifier, reading the
output might be problematical with a nice solid earth on one leg.

You have already heard of transformer coupling I assume, if you are using
bottles.

Jug elements - hmmmmm... nice constant resistance when they warm up?

Just like wire wound speakers.

Does it work just as effectively with toasters?

Quite possibly, but I've never tried.

Never really thought of them but
I assume you've tested them (jug elements that is) for suitability and
stability. Personally I find the average PC soundcard has a bit too much
residual background noise of meaningful noise measurements in high
performance gear, but once again these may only be the limitations of my
PC
and not necessarily yours.

Exactly!!

(I did say *decent* sound card. Try
