Cordovox - I use Audioquest biwire jumpers gold plated high purity copper. You can buy them in gold or silver plated version. Theoretically silver is much better conductor but we're talking about very thin layer of plating while gold is more practical (no oxidation). You can get them from any Audioquest dealer or Amazon: http://www.amazon.com/SET-4-GOLD-BIWIRE-JUMPERS/dp/B005A5Z758/ref=sr_1_2?ie=UTF8&qid=1313469919&sr=8-2
Lack of dielectric is a good thing too.
