Are manufacturer AC cables good enough?

God help the poor audiophiles of yore that made do with very modest fare. Speaking of which, some of the highest resolution, most dynamic systems I have ever heard consisting of horns and compression drivers were running on basic copper wire.

some typical audiophile answers above.

In answer to the OPs open supposition; yes I believe a company like Ayre will voice their obsessively designed and wonderfully performing components to run exactly as intended on the power cords they provide. After all it is essentially the same wire as is found in their components.

not saying a different result can be had. But different does not mean better. It stands to reason the component is voiced with the cords they provided. Otherwise they would state clearly that performance of their components will be improved with an aftermarket powercord.

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.

They’re good enough. My rule is simple. If there’ s a long debate about a tweak. Leave it. Invest in what clearly matters.

About once each year a skeptic is brave enough to try and figures it out. At that rate by the end of the world the debate will be resolved.  ;)

Gosta: Your rule is simple indeed, but flawed. You base it on a debate from other people, AND, you give it a long time to develop. Why not “solve” it once and for all: try something for yourself. Unless you don’t trust your ears, that’s really the only way to know.

And what “clearly matters”? And why is it different than “a tweak”? More importantly, why do you think this “other people” never “invest” in “what clearly matters”?
