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?

But each board also has IC chips so there’s the inevitable EMI and RFI from that.
i forgot to say that adding my golden plate to the S.G. was motivated in the first place by their capacity to decrease the noise level like i was using them already in my house electrical grid to begins with...

But i discover that adding also herkimer diamond or tourmaline to the "golden plate" not only decreased noise level but changed the timbre perception and not only the imaging or the soundstage....After that i discover that they work more powerfully interconnected not only with stones but with my resonators grids...

It is this way that i add to passive material acoustical controls (reflective,absorbing or diffusive devices)
what i called an active non computerized device for acoustical control: the grid of S.G. interconnected with the grid of resonators....

Remember that all electronical devices that are sold for line treatment or electrical control, power conditioner and other device add a noise of their own because they add electronical component to the chain and they are costly... it is always a trade-off...

My "golden plate" cost peanuts and are passive material....

The ratio quality/ price is then over the roof for me....It makes no point for me now to add costly pulse generator for example....

Audiophile experience is NOT necessarily costly, this is my main revelation.....😊

People want to pay 10,000 dollars for a new dac without even controlling the mechanical, electrical, and acoustical embeddings of their actual audio system...

Upgrading is not the solution most of the times or at least for most of us no so rich people.....Embedding rightfully is....😎

mahgister, when you say "interconnected" I think all you mean is they are connected to the same power source, right? What I mean is they are all working independently, not synchronized, right?

No ....:)

They are synchronized by copper cable in ONE grid connected also by cables to my resonators grid....😊

I own 2 that are with their power supply slightly costly (20 dollars), one more costly but USB (50 dollars) and 8 at 10 dollars USB powered....Then 11 in all.... The costly are not really better than the cheaper one, the difference come more with my modification.... And their synchronisation with themselves and with the resonator grids...

My wife think i am nut except when she listen to the sound and she is not an audiophile at all....She is very pleased that i vouch to not buying any costlier component for upgrading, there is no point anymore....I can live with my audio system now....

So @mahgister,

Have you compared the active devices to the passive?


More to discover
