Elecaudio low impedance 0,5mm² multistrand copper wiring, 45 0,12mm strands and an FEP sheath with 1,50mm overall thickness - which I think is about 15 gauge?
I’ve spent a long time looking for a decent cable for my Focal Elegia and came to the conclusion that I could build a better quality one than anything that was realistically in my budget. Multistrand cable is hard to find and my preference is one by a company in the UK but Brexit is rubbish for cost. Luckily Audiophonics exists and has some decent alternatives. I’m going for a gold and black woven cord to match the Viablue jacks.
