Making a ribbon speaker cable takes some work. You need to get some 12 gauge very thin copper ribbon. I am talking about thousands of an inch. Then you need to lightly sand with 320 paper and spray a thin coat of polyurethane. Do this to both sides. Leave the last half inch unvarnished. It is really hard to get this around a post. so I used a high quality rhodium on silver spade. The difference in sound over the magnet wire must be heard.
By the way, I probably will never replace my Speltz ICs.
