Kana, there's several cables available. The jacket is purple and the cable conductors are in a Litz configuration, Teflon insulated copper. Don't know exact model number, though. The Belden site shows them all.
Now which companies use this in their power cords? My AudioPrism Super Natural is purple. Surprised I was while in Detroit watching the 4th of July fireworks I saw *that* purple cable coming in and out of the TV broadcast trailers. Surplus signal transmission wire is the best deal for DIY. My speaker cable is military surplus signal transmission wire, Teflon insulated silver plated copper. The price is 65 cents a foot.
I spent my cable money in Ridge Street Audio interconnects.
