Hi Boris, Ray here, I just recently started to put together my own TT. But on this topic, I bought from Amazon, actually from Knukonceptz their 12 gauge OFC speaker wire. It is stranded with 294 strands in each PVC soft jacket. I was also looking at some Sewell OFC wire same gauge, with 259 strands in it. I didn't buy that, but us tinkerers like to play. So I would after reading that section dealing with wire resistance, I wonder what would the difference be? I was thinking about making up a power cable with this stuff, but haven't determined what two ends, (at the wall and at the equippment) to get. It's been more of a thought. Should I just leave it straight cover it with Tecflex or twist it. It could get bulky in the latter case. When I purchased this Knukonceptz cable, I was thinking at the time of skin effect. So, more strands, more conductivity. So that's all for now.
