If you can’t put a sentence together, or your post is full of typo’s, spelling and/or grammatical errors, I tend to pretty much disregard anything you’re trying to say. Especially when you’ve never even tried the equipment or component in question.
It’s always the same "blow-hards" posting in here with zero experience screaming at the top of their lungs that something doesn’t or cannot work. Usually these people don’t have a system listed. Ever notice that?
If you can’t hear a difference in power cables, great.
Save your money and buy some better equipment.
A power cord can absolutely change the sound of a component. To say otherwise just shows complete ignorance and a lack of experience on the subject.
