Are manufacturer AC cables good enough?

@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? 

You have a beautiful theory.  Expensive aftermarket power cords improve the sonic ability of the component. Now tell us about the experiments used that agree with the theory? Did any of them disagree with the theory? Could the theory be falsified? If so how? 

I have no doubt, he’d have EXPERIMENTED with it!

      
I have no doubt the experiments would have been scientific experiments where variables are controlled. If you dismiss the scientific process why corrupt the memory of a scientist to support unscientific blathering?
