Power cable from wall socket to power strip

I added a 4AWG/per conductor power cord from the Furutech wall outlet to the PS Audio P20 and another 4AWG power cord from the P20 to the high current Steve McCormack modified DNA-1. The increased amperage was well-appreciated by Tekton Design Double Impact speakers. Each of those speakers has 11 drivers requiring amperage to reproduce sound. The additional amperage is all I can attribute to the improved sound. I listen to music at around 50dB and the dynamics peaks are around 73dB…happiness achieved.

This below is the Shunyata cable you may be remembering. I have one connecting my 4 outlet Hydra to the wall. It made a very noticeable difference in sound quality without squashing dynamics. My Hydra only conditions two power cables - to my CD transport and dac. I find that connecting pre and power amp cables to the Hydra steps on dynamics too much.

Since I started this thread I've been searching the internet for information about power conditioners and power cords. I found so many different and contradictory answers and opinions so I wrote these questions that made some here mad at me.
I'm sorry for that. It was not my intention to waste anyone's time and I'm certainly not trolling. Some answers got a bit too technical for me and I tried to rephrase my questions.
But I understand this is not something that has a solution that fits everyone.
mihorns answers made it clear to me that testing is the only way to find out what works best for one and each. As some of you already had said.
And again, I'm really sorry that I upset some of you.

Thank you all!

Trial and error seems to the way I usually evaluate changes I make within my systems, along with a lengthy audition.
