Replacing generic RECEPTACLES

You have hundreds of fat of copper in your home and you think changing the last three feet of that is going to make a difference at what comes out of your speakers….yea, ok

Elizabeth...why should we try?  I've done that with speaker wire and interconnects and found no difference over appropriate and inexpensive cables.  Why waste more money on something that anyone really intelligent and logical would discern as a "gimmick."  Besides, if I tried and reported no difference/improvement, you YaySayers  would retort (incessantly) that my ears are out of whack or my system isn't good enough to "resolve" the improvement.

There’s no reason for you to experiment with power cables - your mind is already made up. It’s called confirmation bias. Your assertion that "anyone really intelligent and logical would discern as a ’gimmick’ " an improved cord isn’t consistent with the facts, btw, but that doesn’t really matter. Your mind is made up.

According to UL and NEMA, the only difference between a 125 vac 15 amp receptacle and a 20 amp receptacle, is the plastic cover governing the type of plug it will accept.

This is mistaken. A 20A receptacle is designed to safely conduct 20A of current. A 15A receptacle is not designed to safely conduct 20A of current.
