Are manufacturer AC cables good enough?

Contact Ayre and ask them directly. They respond very quickly and are happy to answer questions.

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

In case anyone missed it the first time.

Ayre for many years had a line of Ayre branded premium cables manufactured by Cardas if my memory is correct.  They were not included in the sale of new equipment.  I use Audience AU24SEi power cables with my Ayre VX5/20 amp and QX5/20 DAC.

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.
