I suggest Ramm Amadeus 5 MKII for hot and neutral and a counter rotating earth wire around the cable, and combine them with pure copper Viborg plugs (for example VE512R) with the plating that you prefer (gold,rhodium, pure copper). That gives you 11 AWG of high quality OCC copper in an air dielektricum with tellurium copper connectors and the performance of a 1000+ dollar cable.
