Accuphase E-5000 factory power cord good enough?

As a former naysayer, the answer is probably no. Everything matters.

However great quality can be had for a reasonable price and Zavfino is one of many good examples as they sell direct to consumer. Take out the distributor and dealer margin and you get a $1500 cable for $345.

Or buy used.

It should not come as a surprise that many high end audio manufacturers don't supply anything but a 50 cent power cable; it's a throw away item for those in the know, and a cost savings for those that are not.  

@duketbrd88 great, your system at y9our usage mode is not sensitive to power connection resistance increase! Surge protection (xtra) is good, I’ve seen damaged equipment w/o it! 

enjoy the music! 

buy a used pc and try it... asking here will bring absolutely no clarity in your mind regarding the question ... you will hear replies all over the map and confusion and doubt will remain

@macg19 have you seen Accuphase high grade power cables? 

@westcoastaudiophile I have not. The OP didn't mention he had a "high grade" power cable. No mention of this in the specs either. Is this an optional item?
