Are manufacturer AC cables good enough?

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?

I find it rather funny that people who claim that those who hear no differences "have obviously never done the experiments". Does it ever reach consideration that they did do the experiments, rigorously, and properly, and that is why they have proven to themselves a lack of difference?   

djones51, Neil deGrasse Tyson admits that gravity can't be explained! Interesting.....

But we can do experiments showing gravity exists. I am not sure he said gravity can't  be explained perhaps it was we don't really know what gravity is? We can explain the affects of gravity but what it is made up of, gravitons? Who knows.
