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?

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....
I called the S.G. an active acoustical control device...

I use also passive cheap material, for absorbing surface, or creating more reflecting one, or using some homemade diffusive device... They are passive materials...

The S.G. grid is active because electrically powered and interconnected also with copper bowls resonators or small one in a grid...

The passive materials and the active S.G. grid are my 2 main acoustical embedding controls... Acoustical control is one of the main key to S.Q not upgrading most of the times...

In general people have no idea what level the audio system they already have can achieve, this was my case 2 years ago and without money how to upgrade?

My solution was a triple rightful controlled embedding, vibration, noise, and acoustic.... 😊😊

No more marketting hyping tentation for me, and the fun linked to my listening experiments was the cake icing..

Anyway when the jazz orchestra is standing in the room it is enough....Better components exist but diminishing returns exist also...I listen music and even my classsical favorites now, symphonies or chamber music or choir music with delight...It is difficult to listen complex music when the sound is not very good and all details and naturalness of timbre are lost ....

My main reason to inhabit audio thread years ago was my dream of audiophile experience.... with the time passing i decide to experiment with peanuts cost materials and with each month i was discovering things.... At the end it was clear for me that no upgrade can replace the three embeddings controls.... And if some upgrade can by miracle, the cost is out of the reach of most anyway...

Now my main reason to inhabit audio thread is giving hope to those who cannot afford costly gear and dont know how to rise the S.Q. level at minimal cost....

I read no more except by curiosity, for example the Tekton design excite my curiosity but i cannot afford it.... Same thing for Berning amplifier....But happily my audio system is so good that upgrading dont bother me really now....I dont even listen to my 6 pairs of headphones now because they sound less good, less natural and even less detailed than my speakers....I owned electrodynamic, electroacoustic, and magneplanar headphones...Even modified they are no more interesting....7 years ago i was thinking that only headphones could gives me audiophile experience at a lesser cost....It was not true  :) At this time i had no idea about the 3 embeddings controls for my speakers...

 I will be happy if i can help some with my suggestions thats all....
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? 
Use shungite first without copper then listen...The sound may be too compressed... For correction adding the copper tape and the tourmaline stone or the herkimer quartz will do a better job...

Shungite alone tough very powerful beneficial material for audio improvement can work in a too much compressive manner... The use of stones and crystals and copper will compensate and balance the effect... 

Because of this compressive action it is not advise by me to put the golden plate directly touching the amplifier and in some case not also directly on the dac but near it on the cable connector it is ok...It work better on power supply, routers, central electrical panel, electrical meter box, phone box, power conditioner and even behind the speakers electronics (outside the speakers will do near the cables)...  

You must put copper tape on the external side of the application ( for example the shungite side always touching the surface of the objet, the caps of the S.G. for example) you put the herkimer crystal beside the golden plate or on it.... You must listen to determine the best audible effect and the better location for your system... the herkimer directly on the cap of the S.G. will work more in increasing the clarity but on the golden plate (shungite+copper tape) it will work with a more balancing effect on the shungite... You decide by listening experiments...

One step at a time the listening experiments can add incrementally one notch of improvement each time and will dictate to you the right way for your particular room, audio system, and hearing ability....

One sheet thick of copper tape is enough...
