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.
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.
I don't know WHY many things work.
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.
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").
I then collect the sum of the responses and attempt to draw conclusions.
Some good examples of surprising conclusions of the past year had to do with wire gauges for certain applications and the use of ferrite cores on AC power.
After EXTENSIVE testing the consensus (that makes NO logical sense) was that my 8AWG power cords sounded better on EVERYTHING...even low current draw gear like DACs and phono stages.
Silly me...I originally was telling people to follow the LOGICAL and RECOMMENDED path and to use my 14AWG power cords on low current gear (CD, DAC, phono), the 10AWG on higher current draw gear (like amps), and the 8AWG only on very high current draw gear like power conditioners and high power amps.
I was VERY wrong and this was pointed out to me by my beta testers.
I also started making a digital power cord with a ferrite core. Once again, this is what is ACCEPTED as correct with good LOGICAL support.
In the end we discovered that only CERTAIN digital gear sounded better with ferrite cores and that MOST digital gear sounded better with my Cross-Helix and no ferrite.
Now I offer clip on ferrite cores to allow my customers to decide for themselves if the ferrite makes an improvement in their system.
Silly me...wrong again.
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.
Wait a minute...isn't the basis for the scientific process...you start with a theory and then test it?
Possibly that's how it was eventually determined that the world wasn't flat, that the Earth revolves around the sun, that the moon isn't made of green cheese, that man could fly, and that Coke Classic tasted better than New Coke.
Once again, I don't claim to be a genius.
I don't claim to have any original idea...I study the "classics"...I study "new concepts"...learn new things from just about everyone.
I'm just a guy with limited technical expertise and a pretty good pair of ears.
I also have a diverse group of beta testers with diverse types of audio gear that they set up in very different rooms and use to listen to very different types of music.
I first listen to my prototypes and then I listen to my beta testers.
Seems to be working for me so far.
