Are manufacturer AC cables good enough?

21,500 irrelevant posts. Prove me wrong. Provide a link.
Any one will do. Just one. How hard could it be?

Captain Irrelevant: so irrelevant, even when he cuts and pastes, still just as irrelevant as ever. Oh well. At least that was a readable departure from the usual word salad.

The question remains, is he capable of writing anything the least bit informative - in his own words?

If a power cable changes the sound of the amp perhaps your "Ayre Conditioner power line RFI filter" is faulty.

I see. So the conditioner has the magical property of making anything plugged into it sound the same. Power cords no longer matter. Interesting. Tell me more. So I could use lamp cord, or extension cord, it can't change the sound, it would sound just as good no matter what? There is nothing anyone can do after the conditioner that can affect the sound in any way. Not unless the conditioner is faulty. Is that right?

Are you sure you have thought this one through? 

Yes but video runs on NTSC: Never Twice the Same Color.

No matter how I tried I couldn’t hear any difference between the stock and the expensive cable.

You don’t have to try and convince me. I could tell from the beginning you weren’t any good at this.

Hey GK, since you're the expert on relevance, what exactly is the relevance of your long cut and paste job about black holes? 
Oh and you never did give us your reasoning behind why vibration matters. Please. Share. Share. etc etc.

Pretty sure that "electricity runs for miles.... then gets to the magical power cord..." is his sarcastic way of trying to say something without ever having to, you know, come out and say it. 

Since he's afraid, or more likely simply hasn't thought it through, what he's trying to say is those last few feet can't possibly matter. Or the other way he might like to put it, if he would actually put it instead of sniping, you'd have to replace all the wire to the dam. Both of which seem to have a grain of truth even though they are ultimately misleading.

Its true every foot matters. Might even go all the way back to the dam for all I know. It certainly goes as far as the drop line. And according to a couple very reliable listeners it goes as far out as the neighborhood transformer. 

Of course the 5 ft of power cord matters. There's nothing magical about it at all. Its simply that some amount of degradation happens every inch of the way. Minimizing it for 5 ft is an improvement. I've done that in stages all the way back to the step down transformer, then to the panel, then the panel itself, and the meter. Others like I've said have gone even further. For every foot you do the sound improves.

People wonder and get triggered and argue when I say how fantastic it sounds. But you know what? Its only the people who haven't tried these things that get all worked up. The ones who've done it, we all know.

Who is this millercarbon dude? Is he some sort of expert on all things concerning hi-fidelity? What are his credentials?

Same as yours. Credentials are a chimera. I mean that literally: a mythological, fire-breathing monster, commonly represented with a lion's head, a goat's body, and a serpent's tail. I'm not big on credentials. I go by what a person is actually able to do, not by what some administrative bureaucratic sanctioning group of committees says they know. 

That said, here are my "credentials":

You could also read through my posts. Quite a few of them are in total agreement with this one of yours from back in December:

Static and electromagnetic energy degrade the end result(what comes out of your speakers).Every component is affected,cables,power cords,amps CD players,orDACS.The presence of or lack of this energy,is why your system sounds better some days,and not so good on others.

Not too shabby. Keep up the good work.

Those people agree with me 100%. They have decided vanilla and chocolate together is better than vanilla or chocolate. I agree with them. They agree with me.

Now would you like sprinkles or nuts?

not saying a different result can be had. But different does not mean better.

No, different means different. Whenever two things are different one is of necessity better, the other worse. You admit there’s a difference. So what you’re really saying then is you don’t know which is which. You don’t know what you’re hearing. Otherwise you would know one is better than the other. But you don’t. You only know they’re different.

Glad we cleared that one up.

+1 Millercarbon. Every piece of wire matters as does every connector. This thread is like the 80's all over again.  
Right. That is how far back you have to go. That is how far behind the times some people are.

Synergistic Research came out with the Master Coupler more than 30 years ago. Even before then it was known there's a lot more to wire than the engineers were telling us. But the Master Coupler and some others were so clearly, obviously, undeniably better than ordinary wire that the whole debate was settled last millennium. 

For people today to still so out of it, it really is like going back in time to the 80's. The joke is they're the ones thinking they're all Mr Science. Clueless.

Freebie rubber power cords good enough? As if!

 the only way to be sure is to try it in your system.

In case anyone missed it the first time.

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.

My thinking is that Ayre wouldn't supply cables that are inadequate for their components.  Is that thinking flawed?

Yes. But its a common enough misconception. So don't feel too bad about it.

Manufacturers build to a price point. For every tiny little part- cap, wire, resistor, every single part- from manufacturers cost to retail is multiplied many times over. Every little thing is scrutinized to get the cost down as much as possible and still deliver competitive performance. 

Let's say Ayre decides to include a power cord they are able to build for $50. Their cost. By the time it gets to retail that's a $500 item. Maybe you don't like that, or imagine it will only be $250, or even out of the goodness of their hearts you believe they will let it go for only their $50 cost. That's still added to the retail price. 

And everyone runs. The ones who know power cords matter run because they know they can find better. The ones who don't know power cords matter run because they aren't about to pay even $50 for one. Eventually everyone runs. Because, its not just Ayre doing this. You follow your logic and its not just Ayre, everyone is doing it, the market is flooded with these things and the resale value eventually falls to zero. The standard factory power cord is worthless. The baseline has been elevated only slightly, but at the cost of everyone having to pay more. 

The same logic by the way applies to every other component part in the box. Aren't the factory feet good enough? The manufacturer thinks so. What about the fuse? Why wouldn't the manufacturer include a shelf and a rack if it sounds better? Why would they even sell this to me, I live in an apartment, they should include a room and acoustic panels. On and on.

Power cords are included as a courtesy, just like patch cords. You aren't meant to actually use them. They are meant to stay wrapped in the plastic bag in the box to be passed along with the owner's manual to the next guy.
