Plethora of Schumann Resonance Devices

Tried an Acoustic Revive RR-77 a few years ago and have been duly impressed. Since then Acoustic Revive has replaced it with the RR-777 and now the RR-888. Kemp has an SR-Plug. Space Technology Laboratory (Canada) has come out with four different models and there are several different units on E-BAY from Indonesia, Bulgaria, England, etc. There's even a unit from Less EMF being marketed by Sears.

I'm somewhat naturally skeptical, but there's no denying that this little RR-77 box has made the single biggest improvement in my system than any other tweak I've tried (and I have tried a bunch through the years).

So given all the new Schumann based products out there, I would be interested in what's working and what's not. The price range in my personal survey runs between about $70.00 to well over 3 grand. Any help in sorting these products out would be (as always) appreciated.

I have an AR 777 on a linear supply in the front of my room and a 77 with stock supply in the back of the room. That combo works quite nicely in filling up my space. I tried three devices, but that made me feel a little "wonky."

IMO it's easy to dismiss these things, but everyone I've demoed them for has heard the difference they make. (Some have been more impressed than others, but they've ALL heard at least some improvement.)
The Atmosphere is an interesting idea, but too costly for my blood. I know two people who've tried it. One returned it, and the other kept and really likes it, so who knows. Maybe I'll give the 30-day audition a try in the next several months.
