Schumann Resonator

@mapman - LOTS of audio companies mess with the electromagnetic field in their products. It's not just amps but anywhere an audio signal is present. The most obvious is the transformer because of the amount of electromagnetic fields that are present there. And yes they can be manipulated to give better sound. 

You didn’t answer my question.

 " So you are saying placing the device closer to your amp produces better sound? Is that how it works?"

Since this debate has started three days ago, skeptics could have already ordered a SG off prime for $14.99, had it delivered, and try it out to come to an informed opinion instead of wasting peoples’ valuable time trying to divert folks from it after never even experiencing it. It’s fascinating. 

Yes thanks for that we know people are free to buy whatever they want.


Imagine if NASA relied on incomplete data or hearsay to land that rover rather than understanding every detail of what was involved to make it work to the nth degree.

I know people are not NASA. But some are engineers or technical people or scientists who actually care about how and why things work including their hifis and use that to make informed decisions and others benefit from that. That includes me.

It’s all good. Buy away! If some one can tell me the right way to use the device rather than leave it to chance, hearsay or theory, I might even give it a go.

No it doesn't have to be close to your amp to "work". It interacts with audio signals which are electrical in nature. I'm stopping now. Have a good day.
