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?

Listen with your ears and experiment.... The sound waves will not know the price you have paid for your materials and devices controls and will act nevermind the price in a positive way or not...

That’s for sure. Professionally made often times does work a lot better. But also a lot of times its surprising how much improvement there is to be had from really cheap alternatives. Springs, just plain old ordinary springs, are surprisingly effective. Townshend Pods are so much better they’re in another league. But so is the price. You get what you pay for. Which is not always true. But that’s another subject for another day.

So the cheap circuit boards came last night. About the size of a pack of cigarettes, only half as thick, they sure don’t look like much. Took a couple boards from the shop, used a rubber band to hold them on there, plugged one in. Blue lights. No sound. Zero. Just the blue lights. Leaned them up against the side walls about a foot behind me and pointing straight out into the room. Unplugged.

Played some music. Plugged one in. Right away noticed a smoother more natural sound. Hmmm.... unplugged, brittle hard edge. Funny, never noticed that before. Sounded pretty good before. Now sounds kinda flat. Plugged it back in. Sure enough, way better, more depth too. Crazy!

Plugged the second one in. Wow. The front of the presentation has moved forward to where it seems in front of the speakers. Not the whole stage. Just the front. The back extends even deeper than before. Forward can be bad, like aggressive in your face. This isn't aggressive at all. More like closer than forward.

Everyone who hears my system winds up complimenting the imaging. Its even better with the Schumann generators. Especially the sense of space, the size and acoustic space of the venue is a lot easier to hear. There’s a smooth natural sense of ease, which was already quite good but now is even better. If I start to think something is missing, unplugging proves yes indeed something is missing- an overlay of gritty tizzy glare that might once have been mistaken for detail or extension but now turns out to have been noise. Like a whole layer of white noise has been removed. Something like that.

mahgister, you are running 9? This is only two. I’m ordering more!
I run a connected grid of 12.....With my mini " golden plate" on all of them with herkimer diamonds or tourmaline to balance the sound ….😊

The sound dont comes from my speakers and fills all my room ....Without any embeddings controls i remember the first time i listen to my actual dac, speakers and amplifier and i was not moved at all, i was thinking about upgrading 2 years ago without the money to do so...My journey begins there with good electronic components but with my unsatisfaction with them....But most of the times upgrading is not the solution and anyway not all of us can bought costly products.... The solution is : never upgrade without embedding everything before....

I prove to myself that it is not the money invested that makes audio experience good but the listening experiments and low cost materials and devices.....The difference between low cost but good electronic components and very costly one is not so great or different after the embeddings rightful controls implementation....For sure my speakers so good they are are not on the same level than your Tekton....But i can live with mine now.....Not bad for 50 dollars used speakers....😛

My Schumann generators grid is connected to my resonators grid by thin copper cable...

This is my main active acoustical control device.... these 2 connected grids...

i also use passive materials for absorption or reflection and diffusion in passive acoustical treatment.... I implemented each one, one at a time, by listening experiments on many months period....

When the 3 embeddings are controlled in some way any audio system is transformed on another level....The 3 embeddings are all important but the acoustical embedding is the more spectacular.....
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.
At Mahgister's suggestion, I added two Schumann generators about a year ago. They are supposed to affect the listener, not the sound. I do notice a "settled" atmosphere in my room that takes on a level of higher tension when I turn them off. I also noticed sonic improvements but am hesitant to attribute it to the generators.If it's better, who cares?!
Denverfred if you put a piece of shungite on the caps of the S.G. or a piece of quartz, you will feel that the audible effect would be more compressed with the shungite and with more air and refine highs with the quartz, this experiment eliminate the subjective placebo feeling or the physiological only effect....

Shungite will always compress the sound relatively to quartz and quartz will always put some air relatively to shungite or tourmaline will decompress the sound but not like quartz, in his own distinctive way anywhere you will put it anyway... The relative compression or the decompression are not always negative or positive in itself.... The negative or positive effect will be relative to the state of your audio system in your house and room....Then it is very important to balance one effect with another to compensate for a negative direction by one or the other.... Listening experiments dictate to me the way.... It is very simple anyway even if it appear complicate, it is not at all.... Ears will guide you without any irreversible error....

My "golden plate" are made with a shungite plate+copper tape on external side .... I put a small shungite plate+ copper tape on the S.G. caps with an herkimer diamond ( powerful kind of quartz) precisely to BALANCE these 2 effects one with another for a more naturalness of the timbre.....Sometimes i use tourmaline instead of Herkimer....

My grid of eleven S.G. is linked by cable to my resonators grids....This is my main ACTIVE but non computerized acoustical controls....The effects are not small with these 2 grids.... They completely transform the room acoustic....More than only refective, absorbent materials or diffusive passive devices....That i use also for sure....

Acoustic of small room is more than meet the eyes....😊


In history acoustical creation of listening hall is very old......Greek theater for example, or medieval monastery....But for small audio room the rules are a bit more complex, especially with a varied content and with an irregular topology and irregular geometry....

My best to you....
