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?

My $2600 phono amp improved by a notable amount by replacing the power cord with a $39 OFC cable with rhodium-plated plugs. The manufacturer should supply a better cable than the standard dollar cable.
Clearly there are those who cannot hear, or do not care, for the improvement quality wire can deliver. These people can save a lot of money. They should be happy. Why then are they so crabby? Could it be because they cannot hear? And spent a lot of money on sound they do not care for? That would do it.
+1 Millercarbon. Every piece of wire matters as does every connector. This thread is like the 80's all over again.  
Holy molly Dow Jones! You are in every single thread on everything how does not matter. Nothing works for you? Nothing impacts the sound? What are you doing in audio forums then? Can you explain your participation in everything without contributing anything? I tell you what it is: Trolling!
I read this somewhere today. Definition of Trolling:

“practice of behaving in a deceptive, destructive, or disruptive manner in a social setting on the Internet with no apparent instrumental purpose.”

Read this Dow Jones. It applies to you!
