If the system used was the most revealing system in the world. and Randi has their 99.9% pure naked cable, and the lengths are kept very short, my money is solidly on Randi. Remember, the competing cable must sound better, not different.
On the other hand, if Randi is using Radio Shack plastic wrapped copper cable, It may be enough to impart dielectric static degrading the signal. That can be bettered.
