@dekay, I've used the Neotech OCC, for my IC and speakers cables per the Helix DIY noted in a prior posting. For all of them I used 3 solid strands. Effectively 18 awg for the OCs and 14 awg for my speakers (Wirebarn calculator). I'm intrigued by your comment concerning gauge and the quality of sound you hear. Have you made or compared awg gauges to make that determination? Not questioning, seriously interested. To be complete, I stripped the insulation and ran thru 3 Teflon tubes of wire+1 awg for approx "air" as dielectric. Return or neg leads are twisted Neotech OCC in Teflon at +1 gauge to positive side. Helix configuration.
If I wanted to make my own speaker cables, is this a good choice for wire?

I'm thinking this wire and adding some quality banana plugs or RCA connectors to make interconnects. Is 2x16 enough or should I double up? Is shielding an issue? Thanks!
