Acoustic Zen and harmonic technology are extremely good cables that’s because they use OCC single crystal wire which is far superior to anything ofc on the market.
I am definitely
not a member of the Science! Police, however...
If what you claim were true, it should be extremely simple to demonstrate such superiority through measurements that can be translated to audible differences. Can you point readers to any such tests?
Surely the manufacturers of cables that include such wire would be keen to
prove its superiority, no?
