I use 30ga. single conductor unshielded copper IC's and 22ga. single conductor copper spkr. wire. Both are in oversize teflon or polyethylene tubing for as much air dielectric as possible.Speaker wires are bare wire terminated. I use all tube electronics with a 1 watt OTL amp. Results are very good in my system, I would expect similar results in other low power tube systems. With 22ga. wire, keep the length less than 3 meters for best results.
