Anyone have the Answer?

Try this: find a dealer who will let you audition one of those really pricy power cords. If the cord makes a noticeable improvement, your power is dirty and a "machine" will help. Good Luck!

I'll stick to my 4 26,000 mf filter caps per channel, per 100 watts times six (3 amps).

Your question is very straightforward and I certainly understand why you asked it.
Unfortunately, certain users on this site feel like they own it and that they can deride people if a question is not worthy of their response. My guess is that no one will put up with their behaviour in the real world, so they troll this site trying to feed their egos. They usually know what they are talking about, but instead of helping people that know less than they do, they choose to mock them for their perceived ignorance. Luckily, there are many decent people here as well, as is illustrated by the number of actual attempts to help find an answer to your question. And, thanks for asking the question. I was wondering the same thing.

Surge protection won't stop Lightning strikes that's why you have insurance. For normal surges the best thing is have the electric company put a device beside the meter, next best is have an electrician put one in the panel box. 

A $400 scope would pretty much do everything you want.
