Are manufacturer AC cables good enough?


I have two PS Audio AC3 and two Pangea AC 14 cables I don't use.  My thinking is that Ayre wouldn't supply cables that are inadequate for their components.  Is that thinking flawed?

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. 
Everything you never wanted to know about the thorny subject of gravity is contained in this book, pub. 1973. Authors Misner, Thorne & Wheeler. Big guns. That was the golden age for gravity and black holes, following the success of the A-Bomb and H Bomb, you known, those guys had to find something to do.

Well if I could figure gravity out and unify it then I will accept my "Noble" prize when the pandemic is over if I am still alive. 
Here’s a quick explanation. Imagine spacetime is a big mattress and all the heavenly bodies are about the size of golf balls and oranges and sitting on the mattress. If you place a big heavy bowling ball on the mattress those heavenly bodies closest to the bowling ball will slide down a little bit toward the bowling due to the depression caused by the bowling ball. That’s what gravity is, the curvature of spacetime due to very heavy objects. It all stems from the General Theory of Relativity.
