Accuphase E-5000 factory power cord good enough?

Suggest focusing on cables that are in the sound path. The good folks at Accuphase surely would not supply an inadequate cord to feed electricity to the transformers…long before an audio signal is involved. 

Accuphase is a high-end company that I believe would not put a substandard cord on their product. You may hear a difference with other cords, but is it worth the cost or aggravation? Good luck with your experimenting adventure.

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)
