Are manufacturer AC cables good enough?

most manufacturers seem extremely hesitant to discuss recommendations for cables and components they don't manufacture...why it's fun to see what they use at shows and in their own corporate listening rooms...

+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!

Millercarbon: for this usual types / characters, the debate was not sorted out in the 80s, because they were not born yet! You realize these naysayers are broke no-job know-it-all millennials writing from their mom’s basement, right?

And as for the “try it for yourself” thing, they have a solution for that. Something in the lines of “science”, and “I don’t have to go to North Pole to know it’s cold out there”. One guy told me something today about a throwing a virgin on a volcano to see if erupts 😂😂. I call this creative trolling 😂🙄

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.
