Power cord replacement suggestions

@chrisr  Some manufacturers DO recommend aftermarket power cords.  I received such a recommendation within the last couple of weeks from a well known audio manufacturer. Your statement is a bit too general. 

I finally received my powercords a short while ago and am breaking them in. Red for cdp, blue for amp. I will soon compare them to stock, but i have changed many variables lately, ran 2 10 guage 20 circuits to the system, speaker placement, isolation devices, cleaning out ears, etc. So, i will AB compare soon and hopefully it's not a case of the emperors new clothes. One question. With everyone touting "20 amp dedicated lines", why do the aftermarket cords just have 15amp plug ends?  Won't this just choke up the current and negate benefits of 20 amp circuit? Be tolerant, i'm not the brightest bulb in the box.

Thank you, ebm, for your support and wellwishing. As i said , soon i will listen to them more critically, and try to enjoy them, as you stated. Your positive post just warms the cockles of my heart. Unfortunately my mediocre means preclude me from anything other than a mediocre powercord. I am happy for you that you are fortunate enough to rise above mediocrity in your audiophile endeavors. Maybe you can suggest a superior cable that i can save for. Sincerely, Oleg
