Are manufacturer AC cables good enough?

I use Ayre QX-5/20 digital hub, DX-5 DSD disc player, KX-5/20 preamp, and VX-5/20 amp with KEF Reference 1s. I suppose the AC 3 cables should go to the preamp and amp, the AC 14 cables to the digital hub and disc player. I buy used, aiming for 50% MSRP, still that setup cost a fair number of bucks. Surely Ayre wouldn’t comprise on power cables when they’re so obsessed with details like fully balanced, zero feedback, and stepped volume control. Nevertheless, I’ll try the cables.

I've been in contact with folks at Ayre on serval occasions, including a scolding from Charles Hanson for placing a Bryston 10B high-pass filter between my (or maybe his) KX-5/20 and VX-5/20, but never asked about power cords.  I think I understand the logic of millercarbon's argument, and it has altered my thinking about power cables a bit.  Manufacturers do not supply interconnect nor speaker cables, so I rely on Cardas for those.

Thanks for all the thoughtful replies.

Obviously there are lots of opinions about power cords, as well as about nearly every aspect of audio.  I found a few of the comments inane or illogical.  One thing I didn't mention that turned me off the AC3 and to a lesser extent the AC14 is the size and stiffness of the cable, a convenience not audio factor.  

IIRC, I bought the AC3 cables for the JC-1s.  I went from Parasound (JC 2 & JC 1) to Ayre (KX-5/20 & VX-5/20) when I added a DX-5 DSD disc player and QX-5/20 digital hub for Roon.

My impression is that the folks at Ayre listen to and test their products very carefully.  My one interaction with Charles Hansen convinced me he did.  Ayre manuals recommend balanced rather than single-ended connections and often give other guidance about what they consider best practice, but nowhere in one of their manuals have I come across a recommendation to try another power cord.  I think I answered my original question, but I'll try the AC3s with the preamp and amp just to be a good empiricist.

I suspect you're right.  

I haven't looked at this thread recently.  I'm amazed by how it's grown.  Glad I didn't ask about something controversial like MQA.

Not yet.  I'm in the process of moving stuff from one rack to another.

As part of moving equipment from one rack to another I at last connected a Pangea AC 14 to the Ayre VX-5 Twenty amp -- I've misplaced the PS Audio AC 3s and the other AC 14 in the mess I've made during the change over.  I have a bunch of similar looking black cables I grab as needed so I'm not sure what cable came with what piece of equipment.  I think I do hear a bit more detail with the AC 14 installed.  I'll continue to search for the AC 3s and other AC 14.
