Accuphase E-5000 factory power cord good enough?

Until you get someone to assist so as to not deal with confirmation bias, you'll not know that there is no difference. Cables of all sorts are the biggest cash cow for the companies that make them. Profits through the roof.

If you are discerning enough to have purchased that awesome amplifier, trust yourself to try some power cords, and decide what you like. Confirmation bias works in both directions. Since you can try for free, enjoy the process and trust your own judgement.

Duketbrd88,

I use and can highly recommend a couple of Zavfino power cords: Majestic MKII and the Prima MKII, both OCC copper cords.....cryo treated, and broken in to an extent. The Prima MKII is taking longer to break in, the Majestic needed about 100 hours, but the Prima is on 200 hours and still improving....both would be great for an amp.

Also would recommend upgrading your power receptacles if you have not done so already: Furutech GTX-D(G-Gold), Furutech GTX-D(R-Rhodium), or the Oyaide R1.....I prefer the GTX-D(G) and the Oyaide R1.....but several others have disagreed, and strongly support the GTX-D(R)

Forgot to mention, the Oyaide R1 is the receptacle to consider,;not the Oyaide SWX series...big performance difference

from lalitk "I would look into Zavfino and Audio Envy brands".  I respectfully disagree, at least in part.  I have never owned or listened to Zavfino wires, but I purchased two AE power chords at a show. 

They were really cheap, so I figured what the heck.  After a break-in of 50+ hours, they STILL SOUNDED WORSE than the plain-black OEM power chords that came with my Pre-Amp and Amp (both Ayre).  Undeterred, I switched to the Anti-cable Level 3 - finally heard how a good power chord can improve Sound Q. 

I now own four of the A-C Level 3 power chords.  The AE power chords are still in a box in my garage: I tried to give them away on AG, but no takers - I think that speaks volumes.

P.S. I have no affiliation with either vendor.
