It appears that the JW is Speltz Anticables with Cryo treatment. Paul Speltz told me that there would be no noticeable sound difference in different length cables. My guess is it would be the same for the JW's. I have a friend who says the cables are better sounding than the Speltz. I've had both the original Anticables and the Level 3 Anticables. There was a small difference in those. For the money, I don't think there is anything close to the sound of the JW's. I was a long time Anticable user and tried at least 6 other cables while always returning to the Anti's. I even used the $1400 Harmonic Technology Pro 9+ and went back to the Anti's. It wasn't until I tried the MG Audio Planus III cables that I thought the much more expensive cables were actually that much better.
The Cryo treatment is about the only thing different from the Speltz. They do offer a 30 day money back guarantee--don't run a day over, however. I have a JW Reference IC and love it. I also have a couple Teo GC ICs and Cerious Technologies Graphene Extreme SCs and jumpers. In my system, this is a great sounding combo of wires. My friend owns a pair of the JW speaker cables and says they are very good and not just for the money.
