best power cord for mccormack dna500

thanks

When I had my DNA500 I tried a bunch of different cords.
The one that I preferred the most was the Purist Audio
Dominus (Ferox). It seemed to be nice compromise between
a Shunyata Python Alpha and my Elrod EPS Signature 3.

Another cord I would suggest you try is the new Tek-Line
Reference cord. I prefer this cord to the Dominus and
if you don't like it you can send it back.

Cheers

whenever someone asks: "what is the best......", i think:

the best is what you like. since preferences differ, there will be many answers. only you can answer your own question.

audition as many as you can at a price point and then tell us.
