Are manufacturer AC cables good enough?

+1 dodgealum, same with my LTA UL, but as you stated, I think this has to do with the Berning design. Folks at LTA tell me they don’t hear differences and they demo on Daedalus and Spatial. However, on other amps I’ve owned and own, improvements abound. 

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...
