Best Power cord for McCormack DNA 225 or 250


What are some of my options for the best power cord in the $250-$400 for the McCormack power amps. I am running a CJ tube amp in front of it. I was considering PS Audio Perfect Wave, Kimber PK10 Gold, and Acoustic Zen Tsunami 11. Any suggestions would be much appreciated.

Thanks everyone, I appreciate all your responses. I will

check out your recommendations. Have a good day.
If you can swing for the Shunyata Python, that would be a very good pc for the mccormacks.
the Audience is also very good, but I liked the Python the best.
I prefer the Custom Power Cord Company (CPCC) Top Gun HCF over the Shunyata Python on my DNA-1 Deluxe. It's $1K new but can be had for $200-300 used depending on length. CPCC is out of business when the owner retired so you can get them for cheap here on AGON. Make sure it is the HCF model,not to be confused with regular Top Gun. I kept the Python for Surround processor. Good Luck!
