Thanks Jimna, those are my thoughts too and interested in thoughts and opinions from anyone who may have experience with this cable.
The cable is ridiculously expensive and it is not easy to imagine it would provide any real benefit. If there were a general consensus that it could be worthwhile it might warrant some serious consideration.
Already have the line conditioner however it is on a shared circuit which includes florescent lights in another room. I know those lights can/are introducing undesired noise to the AC line and that a dedicated circuit is worth doing.
