Look @ bulk solid core Neotech UP-OCC hookup wire and use bare ends (sans connectors).
You can purchase it in either silver or copper with a Teflon wrap (may also be available in cotton wrap).
I've used the solid core copper 22 gauge Teflon for speaker wire, but I prefer smaller gauge (22-26) in single runs of less than 12'.
I've purchased it from a few venders, but only recall Sonicraft (sp?) right now.
