Good luck. Teflon-coated pure copper is very rare, especially solid-core copper in teflon, not to mention high-purity continuous-cast solid core copper in teflon. So rare that I've never seen it anywhere. Cable manufacturers don't like to make this type of wire b/c it's extremely difficult to extrude teflon over bare copper. It's much easier to extrude teflon over silver, thus the silver-plating. If anyone finds a stash of teflon-coated pure copper solid core wire, I'll buy some off of you for good money, more money than I pay for pure silver in teflon wire.
Forget this "mil-spec" silver-plated copper lingo, b/c most such wire I've seen are mil-spec and still dirt-cheap. This is the cheapest, most common wire one can find pretty much anywhere. There is a distinction between silver-plating and true silver-clad wire, which is much more expensive and difficult to make b/c silver has to be physically pressed with enormous pressure onto copper, not simply plated using electricity.
In fact, if you know a source of true silver-clad solid core wire, such as Nordost, please let me know.
One can get close by using something like Jena Labs wire, which is stranded (I prefer solid core) copper wire encased in teflon-like material (unflourinated teflon according to Jena Labs). I have heard this wire, and I do like it despite its stranded nature. This is stuff is pretty pricy.
Enamel-coated continuous cast solid core copper wire ("magnet wire") from Vampire is very nice sounding stuff and pretty cheap too. Chimera Labs makes some great cables with this stuff, and I've made DIY cables with it with great results. Go for 4-wire braid without shielding for typical RCA interconnect.. I prefer this to your usual 24-28 AWG pure silver solid core wire threaded through hollow teflon tubing, which I have used plenty in the past.
If one wants to go exotic, the enamel-coated pure silver solid core wire from Audio Consulting of Switzerland is something to consider, but I would use multiple parallel runs, a la braiding. Very smooth sounding as far as silver goes.
But if all that sounds too daunting to you, just go out a buy a good cable off audiogon, which can save you a lot of hassel and anguish. If you want silver, check out the Cryotweaks CT Silver interconnect, which is truly great. If you want copper, I recommend Chimera Labs IC, which is a steal.
