Power cord replacement suggestions

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

@Droleg,

Congratulations upon the updates you made to your system (ran two, 10 gauge 20 amp circuits to the system, speaker placement, isolation devices).
I'm sure you know this, but I want to reinforce that one might make one change at a time (baby steps) so you can hear and learn what each change in your system has accomplished. I would think the two, 10 gauge 20 amp dedicated circuits might have been the biggest game changer.

"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"?

Droleg, your 15 amp male plug, cannot choke the current coming out of your 20 amp circuit, a 20 amp male plug looks a little different regarding the configuration that plugs into the socket however there isn't anything that limits the AC draw. A 20 amp male plug is a built in safety feature so to speak, a 20 amp male plug usually has a 20 amp IEC on the other end and can only be plugged into a 20 amp AC wall outlet. Google the outlets and look at the pictures to see the difference.
I hope this helps clear up the confusion?

You should have some fun with those new power cords ;-)

Best regards...

PS- I hope you can find a difference in sound with you new cables. I am in the process of switching out some power cords, if you like, you can try them.
