Covering silver wire for use as a speaker cable

If it's "very fine", I assume you mean very 'thin', as oposed to very 'pure', so just how are you going to layer and bundle it to make large enough conductors for speaker cable? And will you be using a two or four conductor configuration? And how will you twist it uniformly?

And that's all before you figure out how to jacket/insulate it so it is protected from air and tarnishing. If you can do all that, you won't have to worry about shorting ;-)

Why not clear plastic tubing for an aquarium pump? It would insulate perfectly and is primarily just air dielectric, except where the silver wire occasionally touches the plastic.

If you like the sound you could experiment with all the other materials that will be suggested in this thread :^), such as cotton, Teflon, etc.

How heavy a gauge you need (thus requiring more than one strand of the "very fine silver wire" per leg) surely depends on what amount of resistive loss you can support without an ability to compensate through increased volume.

If the amps are very close to the speaker (assuming monoblocks and a separate preamp), you would be able to use very short lengths, and may not need "to layer and bundle it to make large enough conductors for speaker cable".

I am suspicious heavy gauge speaker cables. What problem are they trying to address?

I'd be looking for some natural cotton sleeving.
