You’re right! I completely unplugged my amp from my dirty house AC and it sounded wonderful! For about five seconds. Then it faded out. Plugged it back in. Crap dirty sound again. Unplugged, clean power! But only for seconds! How can I get clean power to last longer???

The concept of cleanliness is a relative concept.... this is my point....Upstream to the amplifier there is muddy waters this is also my point....
Noise floor is also a relative concept...
When you use your tweaks on your different gear and on the electrical panel you decrease the noise floor and let the signal then better be perceived out of the decreased noise level.... That is my point but you know already that....
