Anyone have the Answer?

I thank everyone for making a good faith effort to respond to the question I put out. It was in the first sentence for those misguided.

There are some good thoughts and some less practical- unless
you are already in possession of the $10k Fluke instrument suggested.

I have had fairly good luck in the past reading through a myriad of
AG responses and deciding which way to go. I think anyone reading
this thread may begin to understand why I even pose the question.

If I thought the idea was all "Bunk" i wouldn't be wasting time on it.
I think it is probably valuable but I am not spending a dime until
someone shows me. Love the MO folk.

I do have two dedicated 20 amp lines. Now are those for analogue and digital or for audio and video? Heard both ways. Pls explain your position if you have one.

The straightforward solution to any audio uncertainty is to buy one
on a trial basis. Not always a practical solution however.

I tend to think that there are enough experienced people reading
this forum that if I read all the replies carefully, I will find one that
is most helpful. I thought I had a well worded question but maybe not.

Believe it or not this method of learning has been working well for me over the past 5 years. However as I mentioned this particular question seems to stump people more often than not. 

I think my next move will be to reach out to the Shunyata people
to get their take. Good suggestion-thanks! I will share what I learn.

Eric- I fear your answer must be the closest to correct which is
why no one else tries to respond.  Way over my head. 

Thanks all!!

MC-you keep rattling off garbage and most people think you are a fool. You turn a simple question into some BS propaganda that doesn’t relate to anything and you put people down in the process. We all get a good laugh out of your silly replies so don’t stop, they are also keeping the aliens from talking to us. Just like somebody mentioned to you before: have another drink because with each drink your system sounds better and better

p05129 Yeah, I really don't understand MC, he does have some very good experience and knowledge to share, he even thanked me once for a musician I recommended on another thread, so I know he has a heart. But for some reason likes to trash/insult people, especially new people here, or sometimes simply goes on a rant that is not at all helpful to the OP. Maybe could use a friend up there in cold and damp Seattle to warm his heart up a bit more. Or a better Bourbon. 

There are some very useful USB oscilloscope add-ons for computers, about $65. Plenty accurate enough for taking a look at your incoming ac power. They can record on your computer screen Hz and voltage excursions. 

After that, it depends on how clean and robust you want your power to be. The PS Audio Generators rectify and filter the incoming ac. Then it has precision inverters to rebuild the 50/60 Hz to very precise % with virtually no noise. It produces a very exact sine wave at 110/120 vac that doesn’t budge at all with your load. Clean, noise-free, unwavering ac voltage, sine wave, current, and frequency. Even if your power line goes down to 20 vac, 45 Hz, with lots of noise, you’re going to get 120 vac/ 60 Hz clean to your load.

OK time for a new guy with limited audio knowledge to ask a stupid question or two to try to get some elementary understanding as I am obviously missing something.
if you turn up the volume to the max while not playing music and hear nothing -0- from your speakers I would think you do not have a noise problem. Further, when playing music at various volumes and you hear no noise I would think you do not have a noise problem. I say this as I just did it and that's what I heard lol.    So given the above how does the electrical noise negatively affect the sound if you can't hear it?   What is it affecting negatively, the dynamic range,  imaging, soundstage, etc.? What's the science say.
As an aside  I would have hoped by now audio manufacturers would have addressed this issue in their amps as dirty electricity is a universal and persistent issue. 
Be that as it may the idea of a uniform electromagnetic wave
 flowing thru the system versus one with irregularities seems desirable.
