I won't tell you who sells magnet based AC filters and grounding devices out of respect for the owner of the company who is a friend of mine.
Then you should never have made any mention of it at all.
He doesn't engage in forums and he warned me about the same.
Apparently he told me that there are some people on forums that seem to know nearly everything about everything and make it their mission in life to explain away anything they don't understand whether or not they've personally tested it or not.
It's been my experience that it's usually the quacks and charlatans who avoid the daylight. If the claims are legitimate, they won't be able to be explained away. If they can, then the claims being made clearly aren't fully fleshed out.
I don't know WHY many things work.
First you have to define what you mean by "work."
Do you mean "work" as in it produces an actual audible difference or improvement? Or do you mean "work" as in someone simply subjectively perceived some difference?
If the former, then you have to first determine that the thing you're talking about actually does "work." Otherwise you'll never get to the WHY part.
If the latter, then there's simply no point in even wondering WHY, as it could be any number of things including purely psychological reasons.
I do know that when I do my R&D testing I am as objective as possible and try to make IDENTICAL components with only ONE difference between them.
As long as you're just relying on your subjective experience, then you're not being objective in any meaningful sense of the word.
Once I come up with what I consider to be an improvement I then send it to my blind testers for comparison (they are "blind" not "deaf").
If you're sending it to your testers and they're comparing it to an old version, then they're not blind at all.
Lucky for me I have beta testers with minds and ears of their own to straighten me out when I THINK I know what I'm doing but obviously don't.
All you're effectively doing is marketing research, not establishing whether or not there's actually anything going on.
