As that seems to be the position of those who dispute that cables makes any worthwhile difference!chebby said:nopiano said:Hi Chebby. Isn't that a bit undermined by them offering a least four different sizes? I take your point that for a standard living room, the spec you quote should be fine. And for a cinema system you might use thinner, to fit around the room. But why 6mm, unless you are wiring a ship?!chebby said:No, just high purity (OFC), multi-strand copper of an appropriate gauge for the length used (1.5mm squared or 2.5mm squared cross-sectional conductor area in most cases). Low resistance, low capacitance and low inductance. It needn't cost much. I have looked at a few examples this morning costing between £2 and £4 per metre.
Costs £49 for 25metres from RS if you are doing an installation ...

I believe my link is for the 2.5mm version.
Speaker cables have to be low resistance or they will drop voltage. This is not the case with interconnects.
