Acoustic Revive RR-77, 777, 888 Schumann Generator

On the advice of member Mahgister, I purchased 2 units off of ebay about one year ago. Each one sits atop one of my speakers because that happened to be the recommended height. Yes, they have a definite sonic effect that is more than one dimensional, but simply put, it seems to remove some kind of subliminal noise within the music. The effect makes listening more relaxing and focused for me. I have not unplugged them since the day that I bought them.
The units that I bought are actually more powerful than the Acoustic Revive units. They were about $80.00 each. There are other units available for much less. 

I own a RR77, 777, and a 888. When they are turned off the soundstage closes in somewhat. Hard to explain, hard to believe, but they are effective.

There’s a bunch of these on Amazon. They’re on basic printed circuit boards from as little as $13. Nobsound has the same PCB with a little acrylic lid for $50. The Acoustic Revive has the same PCB inside a much nicer looking but still cheap plastic case, $450. (Ted Denny takes the cake at more than twice that. But I'm sure his has a bigger power supply. It certainly looks the part.) It sure looks to me like these are all the exact same thing with the only difference being the power supplies. They all have a circuit, looks like it generates the frequency signal which then goes through a very long winding circuit trace that functions as a sort of rudimentary transmitter or transducer. Depending on whether its electrical or acoustic waves I guess. Some are round, some are square, they use batteries, wall warts, USB, but its all the same at the end of the day.

So what’s the deal with these things? I mean, besides they work. Too many reliable listeners saying they work to deny that. But what’s the deal? Can I really get the $13 board and go swimming in the all-enveloping sound stage?

What say you, resident expert mahgister? I’m buying and trying whatever you recommend. A link would be nice. Will this one do? https://www.ebay.com/itm/FM783-7-83HZ-Schumann-Wave-Ultra-low-Frequency-Pulse-Generator-Helping-Slee...

Millercarbon except for 3 more costly one i use 9 of these around my room in a connected grid with my "golden plate" on top of them....

They work for me....

i connect them to different size copper resonators grid and that improve greatly the audible effect.......

But my room is much different than your room....

My room is smaller, with a complex acoustical content, a different geometry, then you must experiment with these....

My system is not on the same level than yours but with all my embeddings controls it was transformed....Perhaps your system already very good and more than good, will not be transformed on the same level than mine with a grid of S.G.

You try 2 and report what you will hear....If you hear something positive for the cost it will be more than good....  :)

Buy at least 2, they are cheap, and try them at 5 feet high, experiment and report....

My best to you....

Okay I will get 2 and see how it goes.
Thanks!
