Covering silver wire for use as a speaker cable

Nsgarch, Thanks for the suggestion. Where can I buy 4 foot lenghts of shrinkable tubing? And how do I fish the wire through the tubing?

Dgarretson , Where can I buy the cotton sleeve, and wont this be also very difficult to snake the wire through?

Reference Audio Mods has it. Bend back the tip to make a tight curve with a smooth point and snake it through. If you want to send several strands together through a single sleeve, wrap the tips tightly in teflon tape. Be forewarned that jewelers silver may not sound as good as silver made specifically for audio.

Shink tubing is available at electronic parts stores (B+M or online.) It comes standard in 4 foot (or maybe it's 5 foot) lengths. I suggested it because you can get it large enough (in diameter) to easily snake the wire through, and then it will heat shrink to 50% of its original diameter.

It is made of polyolefin which I have to assume has great dielectric properties since it's used to insulate wire ;-)

Thanks for the suggestions. I am going to give them a try.

What size should I buy ?
