PS Always worth noting that when shyster ideologues like James Randi put up money to prove there are no differences they insist on cables that measure identically and refuse any that don’t as they know they’d lose the bet! There was a very heated exchange a while back when Michael Fremer was refused the challenge as he wanted to use cables he knew he could tell apart with 100% accuracy as, unsurprisingly, the cabes in question measured differently, as so many in the real-world audio market do. This is just basic science, not magic!
