In addition:
If these cables actually did what is claimed, every company in the world that utilizes cables, every power grid, every military, every aerospace entity, would be tripping over each other to use this ’secret technology’, yet as far as I know their sole market is selling it to the tiny niche of guys who listen to music.
Anyone have an opinion as to why that might be? Anyone?
I am no expert in any of these fields, but I don’t think so.
With transmission lines it is just easier to bump the voltage and reduce the current to reduce losses over long distances.
*Actually, utilities in my area have been going back to using aluminum instead of copper for the cost savings, they just use a larger size and anti-corrosion goop.
With anything else it is probably more cost effective to increase size of the conductor than treat it with whatever to increase its conductivity/lower resistance than zap it/pulse it with high voltages, infuse it with carbon/xxxxxx, or apply whatever this secret sauce might be.
it’s worth stating: Our ears are more sensitive and accurate than any human built instrument.
