Homegrown Audio sells 22 gauge, solid core, teflon insulated silver for $2.80/ft. 50+ ft would be $1.80/ft. I agree with Dekay, the cost would be too high for a DIY. At least using 30 gauge. With 22 ga., it would be cheaper. But still... You can find silver power cords from Delta, for $125-$200. I got one on this site, and it sounds the best of the cords I have(Synergistic, Coincident, Delta copper). It is 13 awg. Best for source components, but sounded great on my amp. If you really want a heavy gauge, silver DIY, I have a suggestion: Buy 8, 10, or 12 gauge silver wire(not sure of the purity, but may not be the highest) from a jewelry supply house. Last time I checked, 1 ounce was $8.95. 10 gauge is 2 feet/ounce, 12 gauge is 3 feet/ounce. Insert the wire in oversize teflon tubes(gives you an air dielectric), get some good connectors, and there you go. The wire cost would be $80.55 for a 6 foot long, 10 gauge power cord. You should probably also contact Kevin at HomeGrown Audio, to see if he can sell you the wire, with the teflon insulation. He may offer it at a good cost. Who knows? Good luck!
