According to the books I read, the depth of skin effect in copper is less that half a millimeter. That is about 20ga. Under 20ga. should make the entire wire run at the same speed with no skin effect. With a 3 meter run, I doubt you would burn them up from heat, as there is very little resistance in 3 meters of wire. Some say that the thin wires sound brighter and lack bass punch. I would say that you would have to try some in your system to determine if you like the sound or not. It appears from reading these posts that the cable industry has become the tone control industry for audiophiles. Since the gear has no tone controls, the owner makes his tone adjustments with his cables. I guess this is fine, but they are rather expensive for this purpose. The late Harvey Dr.Gizmo Rosenberg said that his 18ga. silver solid wires beat hell out of every five thousand dollar wire he had ever heard. But we all know he listened to a low powered SET amp and Tannoys which add up to a high-end challenged system, which is maybe why he needed a bright cable like that. Have fun!
Speaker wire guage/current draw ?
I have a 200 watt class A amp and power hungry 86db 4 ohm speakers.I'm using ten foot runs of AWG 10ga cable.My question.....Your house wiring is based on a strict code to detemine the proper size of the conductors.Iv'e been tempted to try some of the smaller guage silver wires popping up nowadays and have read the threads regarding the OTA from Sakura.....Certainly there must be a determining factor in choosing a speaker wire guage or can you really hook up your Wilson's and Krell with 26 ga wire?
