I found the following in another thread regarding the use of 12 ga. Duelund wire. The thread is titled "Doug Schroeder Method, Double ic" and posted by

I then decided to try building a set of double-run cables using 12 ga. Duelund hook-up wire and Rean RCA plugs, which is what I had on hand. If you are thinking "is it possible to fit four 12 ga Duelund wires into a RCA plug" the answer is yes it is possible, but it is a colossal pain in the ass. I really wish I had paid Bill Dion to do this job and spent the day doing literally anything else. It took me about 7 hours and I never want to see my soldering iron or this Duelund stuff and its cotton insulation again. Argh.
The results though... totally worth it. Wider soundstage, better separation, tighter bass. I’ve only had them in for an hour, and I can’t remember if the cables I cannibalized for this project were broken in or not, so we’ll see what happens there.
