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?

I don't expect hobbyists to be conducting scientific tests but think it's NOT unreasonable for PC manufacturers to publish test results supporting their claims. Is that too much to ask?
There are companies such as Wireworld that have conducted blind tests - WW even developed its own comparator so you can listen blind to your heart's content, and then decide for yourself. Is that too much to ask?
Which Wireworld, the one that claims lots of double-blind testing, even though they makes lots of excuses for it, but to my knowledge has never published actual testing and/or had fully independent listeners participate in the test and allowed the results to be published? That Wireworld?   Or would it be the Wireworld that erroneously uses the fact that humans can perceive ear-to-ear timing differences as justification that fast speed in cables is important, even though the two are completely unrelated?  Perhaps it would be the wireworld that claims that the small phase-shift at high frequencies with "some" cables causes things to sound "bright" due to prolonging the sound, even though phase-shift in speakers is in general way worse than any cable. Or, is it the Wireworld that claims triboelectric effects are an issue, though it is easily shown through calculation, measurement or experiment, that with the typical source/load impedance in audio, that triboelectric effects are meaningless? .... Which particular one?

Synergistic Research also claims to do exhaustive double blind testing, but again, never publishes anything, nor allows independent verification.
You sure ask a lot of questions. What are you, a narc? Independent verification requires someone uh, independent. That’s why they call it independent verification and validation. Are you volunteering again?

"Synergistic Research also claims to do exhaustive double blind testing, but again, never publishes anything, nor allows independent verification."         Excuse me? Synergistic offers a 30 day satisfaction guarantee, on virtually everything it sells.       That should be sufficient time, for even the most obtuse, to discern whether a component change results in an audible difference, in their own system.      Ever been to an electronics trade show?    Mr Denney goes to lots of them, around the globe, at which he demos his wares, openly, proudly and with great success.     ie: https://www.synergisticresearch.com/best-of-show-awards-2015-all-major-shows/
