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?

Having used two of them for months now, I wouldn't describe the effect as just one frequency extension or depth of image, although those seem improved. For me, it is as if the music suddenly became more organized, and something "busy" in the music disappeared, leaving a natural flow, and exposing rhythms that I hadn't noticed before.
oldhvymec,
I'll be interested to see what you think. I'll bet that you won't want to be without them.
Gee pindac, I hope that you don't take that long to decide what to have for lunch...you'd starve!
oldhvymec,
I can understand your curiosity, as I was really fascinated at first too about how SG's worked and why. I still am of course because I really don't understand why they work, just that they do. 
When it is pluged in, you can hold it and feel nothing, and put it up to your ear and feel nothing, and yet the effect on your perception of music being played is immediately noticeable. Why don't you try a couple? I would be interested to see what you think.
I'm considering getting one for the bedroom to see if it really has an effect on my sleep.
Hi Mahgister,
I happen to have copper tape that has adhesive on one side, because I make stained glass panels as a hobby. When you say to put the tape on the external (up side) of the Shungite plate, how much, and for what purpose? Should I use some to adhere the Shungite to the acrylic case of the SG, or between the Shungite and the Herkimer crystal? 
Mahgister,
Since you were so right about this the first time, today I ordered Shungite plates and Herkimer crystals for my SG's

Miller,
I'm glad that you find it effective too. I'm very grateful to Mahgister for bringing it to my attention. It's so inexpensive for what it does.
Congratulations speedskater! Only 5 posts and you're already a know-it-all! However, I regret to tell you that these "toys" still do work.
Hi Miller,
According to all that I have read, about 5 feet is a good height, and as I said, that happens to be about the height of my speakers on their stands. I would definitely not place them on the floor.
Yes, as I said, I think that they are something that is affordable and effective.
Ozzy- When I ordered mine they came within a week. I bought that particular one because it was built better than some of the others. It might be worth the wait.
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.
