Acoustic Revive RR-77, 777, 888 Schumann Generator


Love to hear from anyone about their experience with these devices.  Long story short, I have an RR-77 in my room.  Bought it off Audiogon about ten years ago.  Every once in a while I look at it and think to myself "stooopid".  So I turn it off... then back on... then off... then back on.  Then I leave it on because what it does is wild.  And it does wildly good things to the sound in the room. I have it positioned above 5', and off to the side in the room.  It's like an ECU tune on your already high performance engine.  It's like buying a chocolate from a storefront in Brugge, rather than a Godiva from your local mall.  

I've read the threads.  Looked over posts and reviews on the interwebs.  It works and anyone who says it's snake oil... whatevs.

Anyone ever compare iterations of this device?  77 vs. 777 vs. 888?  Any discernible improvements?

I have not delved into any other AR devices.  Anything particularly noteworthy?

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....
roxy54,
Looks like a good unit to try, I thought of placing an order, but it looks like it might not be sent until February 2021!
