Are manufacturer AC cables good enough?

 As one notable, Physicist, theorist and Nobel Laureate is usually quoted, " It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong."      THAT’S, "logic".

Who is this notable Nobel Laureate? I doubt very seriously if his criteria for experiment is put a cable in a system sighted and proclaim the sonic superiority of the cable. Physicists, theorists and Nobel laureates use stringent criteria for experiment. 

Too lazy to copy/paste something, in your search bar?     Typical naysayer, to ignore something so simple!      If he ever owned a sound system, I have no doubt, he’d have EXPERIMENTED with it!       Your ilk is an embarrassment, to the scientific community, not to mention: a waste of keystrokes. https://www.brainyquote.com/quotes/richard_p_feynman_160383

@freedomgli and @rodman99999 : stop feeding the Troll. You will get nowhere. It will continue to be a circular argument going nowhere and you will accomplish nothing but empower him on his anti-audio hobby

Come on, guys. All you need to solve this sticky problem is a Poet Laureate and ten consecutive controlled blind tests. 🤗

The embarrassment is in using a scientist to support unscientific nonsense. Let's  use Feynman, in your words tell why does a $ 1000 power cord sound different than a $10 power cord of equal gauge?
