Steve great idea. This would acually be similar to the Mobie cable burner, which passes a large amplitude square wave through the interconnects into a dummy load box. I got my Mobie from Music Direct in Chicago; list price $250, I think I got about 10% off, but I had to beg for it.
Laz this Mobie is what Sean recommended to me, but it only cooks interconnects, no speaker cables nor AC cords. He recommends 30 days for best results, but even one day reportedly helps.
