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?

The PCs provided are adequate. They are not great. The serious audiophile will replace them all. 
"Power cords are included as a courtesy, just like patch cords. You aren't meant to actually use them."
Some of the wisdom found on Audiogon should be in the Library of Congress.
I know this is heresy to true believers, but AC cables, if good quality, are all very similar.  At minimum the $300-+++ you will spend can be put to vastly better use elsewhere. I have a very expensive, revealing system and find many claims to be bunk.

Hi @itsjustme, I am curious to learn what your “very expensive, revealing system” is. Unfortunately I see you have not posted it under Systems
