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...
