Power cable education needed


Hi everyone. I need some education on power cables. I have been reading that a good power cable is vital to a good sounding system. If that is true wouldn’t the companies the make the components include a good power cable to insure their product sounds the best that it can ? Should I evaluate the power cables in all of the components in my system?

Power cords with better shielding, and build integrity don't make a difference. What?  I would rather have a better power cable on my equipment because they are made better, and if there is an improvement in sound, then that's even better. By the way, I do hear changes in the sound, which will depend on the cable being used.
@edgewound,

your offensive language is in no way acceptable given the irrelevant and dodgy test method you quote. It is this overreaching and obnoxious behaviour that makes me wonder whether a rational argument can be had in these fora. Disgraceful and silly.

I apologize if I hurt your delicate feelings.
My friends that work at JPL and managed to stick some landings, rovers, a remote control helicopter, send photos, and a few other little experiments laugh at these conversations and claims that can’t be backed up with one iota of science when it applies to audio frequencies.

Believe what you will...I’m not buying it.
Good to know you have friends in high places, I have got ears...
Apology accepted
