I guess that this is open to anything if cable deniers are welcome.
There is such a thing as Fire Alarm cable.
It is bare (good) solid copper (good) with polypropylene insulation (good) and a PVC jacket, which it would be better to remove to lessen the capacitance. It comes in gauges like 18, 16, and 14.
It has the scientific characteristics that you would want in a hi-fi cable, at zip-cord prices.
It costs about a quarter a foot. You just have to find cable that is polypropylene (some of it is vinyl) and a distributor that will sell you less than a full roll.
