Don't be fooled by the the title "Wiring Cable" !! Use this wire in power and speakers cables. For power cable just enclose it to a hard hose not to bent and use pure copper plugs. Don't use any kind of shield!! For speakers cable twist it 7 twists per meter and use it without plugs or with good quality ones. This is the best audio cable, it beats cables costing many thousands. Companies just don't use it because of it's easy to bent character.
I have made many power and speakers cable using this wire for me and my friends. I have also build interconnect cables using SOCT 18 wire in pseudo-balanced configuration. In direct comparison with many expensive cables those cables have completely no sound character, no coloring, no hi-frequency harsh, excellent tonal unity and the best bass control. Don't use those cables to "tune" problematic sounding systems, these are completely neutral and transparent cables let you to hear your Hi-Fi/Hi-End gear.
