I haven’t heard these products. I have no argument with those who own them and perceive a benefit to having these cables in their system. I’ll have to admit, however, that I’m not smart enough to understand how these cables could benefit your system when they are not actually attached to your system. We all believe as we will, but I think that assertion will cost this vendor a lot of credibility with most people. It Certainly seems reasonable if there is an “effect“ that “lingers“ but then dissipates over time after the cables are disconnected then that “effect“ should be measurable and it’s dissipation should be measurable.
