I have used a cable cooker on all kinds of cables. Expensive speaker cables, inexpensive speaker cables, expensive interconnects, inexpensive interconnects etc... Everyone involved agreed on every cable that it made a substantial difference. I wouldn't be without one. I usually cook the cables every 6 months. I cook a cable for 1 week for the first time on a brand new cable. Then 3 days for each "tune up" every 6 months. I really wonder about the people that say they can't hear a difference. I hope this helps you and I hope I didn't offend anyone. Happy Listening! John
