Can upgraded power cords help my setup?

I own Krell, Bryston , McIntosh, electronics!
Spent thousands on national brand cables ! Stick to custom made cable makers! Same or better results for 1/3 the money!
My cables from Walter Wegrzyn Cable Co in Mesa Arizona! Custom cables , incredible quality, won't bankrupt you!

Power Cables

High-end power cables are seriously a thing. I'm not kidding. If you believe changing the power cable in your gear will improve the audio or video...I have an island I want to sell you.

In short (so to speak), power cables have no effect on audio, video or any other kind of fidelity.

Helomech: I'm tossing the ball in your court! I got thrown out for referencing a leading authority on high end! Hold down the fort!

Boxer12: I was advised my response was naughty! They removed it! I'm exiting stage right! Power away my friend!

Geoffkait: A large portion of electronics is personal taste! The power of the mind can move mountains! I bought a Pangea Amp power cord ( like 8 Guage ) and connected it to a Anthem amp! I noticed a change in sonic capabilities! My belief is the change in amperage flow (to unit ) that does it ! It's amperage that kills you with electricity vs Wattage! So do power cords give blinding change to sonic reproduction! It's your money, and your belief! I own Cardas clear! 4 figure power cables! Do the clear improve my system by 4 figures! IMO NO!

Corporations provide units at no cost for review because their opinion can drive sales! Not all reviewers are on the take! I tend to follow their advice! I hold multiple (2) degrees from Penn State associated to this subject! Please tell me why I'm wrong!

Randy 11: Your opinion and your prose! I'm a associate professor and fail to follow your diction ! I will turn your rhetoric over to geoffkait and boxer 11! At least they can decider your enigmatic prose! Please refer to last two words!
