The electricity I receive at my humble abode is generated over 100 miles away. . . How on gods green earth can a 6 foot cable running into my amplifier make a difference?
During a two week rafting trip down the Colorado River - through the Grand Canyon - we drank water only from the river - lots of it. No bottled water. The river was hugely contaminated with viruses, bacteria, protozoa, waste products and who knows what else. Thanks to the last 6 inches of the reverse osmosis pump filter, nobody got sick - ever. I did that rafting trip twice.
Just like a household filtration system, the drinking water in the kitchen is filtered at the tap - just before the end user. It’s no different for an audio system.

It’s important to understand that digital audio components themselves create noise - which is regurgitated back into the system circuitry. This, in turn, pollutes the other components. An audio system is its own ecosystem. The noise isn’t just coming from the utility company. Much is home-grown.
I use quality power cords in conjunction with quality power conditioners to clean my power. My ears tell me that it’s working quite well.
