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?

Ditto for "audiophile-grade" fuses! Anybody like Ted Denney that can sell painted fuses for hundreds of $$$$ has got some balls!
So then can you please explain to me what these giant power cords bring to the table? I purchased a couple and I couldn’t notice a difference. I’ve got good hearing and approximately 50 K in my system. I’m trying to figure out what a $10,000 Power cord brings to the equation. I’d love to have an explain to me. Thanks

Come hear the ones I have. When you scrape your chin up off the floor take a minute to regain your composure and then explain to me which you would rather have: that sound? Or the explanation?
There is not one shred of evidence that aftermarket power cords do anything to affect sound. 
Yes the can have effects on power supplies.
Many say that why get a better pc since what runs through the walls is crap.
First make it better and second everything starts in the power supply of a component and not outside our houses. 
Build it, component, wall outlet, through the walls, circuit breakers, panel, whatever, one step at the time if not all together. This is what i have learned.


Stay with the pc the company supplied with the gear? That makes no sense to me. I've seen the  prices for these freebie pc's,  600 bucks for 1000 cords or 1000 bucks for 600 cords thicker gauge, all from China I'm sure! There not worth the trouble to scrap and will just wind up in a landfill. I like to hear Allen Shaw rant on power cords, my favorite.
