Are manufacturer AC cables good enough?

I have tried numerous power cables including AudioQuest, ESP, Shunyata and a few others on the Aesthetix Mimas integrated amplifier and none of them were any better than the stock power cord from Aesthetix. In fact, they all negatively impacted the sound.

On other components like the Ayre Codex, Ayre AX-7e and the Ayre EX-8 the AQ Hurricane offered a big improvement over the stock cord. The impact on the DAC was the most notable. I think the only way to be sure is to try it in your system.  Good Luck!

+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.

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.
