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?

Sorry for that important part indeed...

I apologize and wish you the best....

:)
My dear friends here, i must say something very clearly: i dont know HOW exactly my main devices work in function of precise law of physics...

And anyway many engineers, which applied the laws they know, sometimes dont know either...

The majority of people read reviews, about the new technical design of the day, for example the Berning ZOTL technology that interest me very much, but majority of people cannot understand the way the ZOTL technology function in contrast with many other tubes technology.... They bought with confidence in the designer and in the reviews and they pay....

I am like all these people, except for one point, i could not afford what i really want to upgrade to at these times, then i have only one last choice to upgrade my audio system without buying anything, and this was improvise my own solutions with low cost materials and homemade devices, very simple one...For these trying set of experiments with some unorthodox materials sometimes ,one thing was very important: listening experiments... No reviewer was necessary, only my ears and trust in them to reach my heaven and finally erasing my unsatisfaction...

The fact is that i have succeed to my satisfaction with many experiments, some crazy, that are described in my thread about "miracles in audio"...My real journey begins 7 years ago to choose the right electronic components for me.... It takes 5 years of trials and errors.... I succeed partally.... I was not completely pleased with the end result, even if i have known and even if i knew after my thousand hours of reading that my audio system was indeed very well choosen: Sansui Au 7700, Mission Cyrus 781 speakers, Dac NOS Starting point systems TDA 1943, but anyway something was missing in the sound, in fact many aspect of the sound were missing or lacking...WHY ? These components were very good i knew that.... Then WHY?


In the last 2 years i discover that the main KEY factor in the audio life in not only and mainly the wise necessary choice of some electronic components, and there exist plenty good one to choose if your inform ourselves anyway... Then it was not the choice of the electronic component the main factor of satisfaction after all..


The key thing was HOW to EMBED the choosen audio system in all the mechanical dimension.... In this dimension all vibrate and are resonant... How to control that in some measure? It was particularly important for me because my speakers are on my desk with the amp and the dac....It takes me 3 steps to solve that to my satisfaction : the multi layered sandwiches of different materials, the damping loading of my speakers, and the righful use of  fine tuned compression of springs....

I realize after studying that the electrical grid not only of the audio system, not only of the room but also of the house produce a too high noise floor, and  then the S.Q. was evidently attacked by noise pollution...How to care of that without money? I succeed by devising my "golden plates"...

I realized by trials and errors the impact the room acoustic has on my impression of the sound, i realized that the acoustic of a room is more important that even the design of most speakers if they are well designed already to begins with....No affordable speakers can sound good in a bad room....No speakers beat the room....

To be understood clearly i called these 3 dimensions where any audio system is immersed, worked through, and sing, the EMBEDDINGS of the audio system...

I devise step by step my listening experiments, in these 3 dimensions, the simplest one was the mechanical dimension... The electrical grid dimension was more difficult but by a stream of luck i devise the right product to do partially but successfully the right thing... This was my "golden plates"...

For the acoustic dimension the experiments were longer and more complex.... I use passive materials and active devices, interconnected together, step by step, the main active devices was the modified cheap chinese S.G.all interconnected with a resonators grid...I will not go to all details here it is in my thread....

At the end after the 3 embeddings of my audio system were partially solved at my satisfaction, i say partially because i dont doubt that there exist better solutions than mine, but not cheaper one tough, i was flabbergasted by the final results.... There was no comparison between the same audio system before my embeddings controls implementation and after...

I then concluded with my audiophile law: Dont upgrade anything before everything is rightfully embedded in the mechanical, electrical,and acoustical dimensions where the audio system is living, is immersed and interconnected also....

Like i said a bunch of costly " tweaks" is not a method of listening experiments....Then i created the expression "embeddings controls devices" to be clearly understood about my point and distance myself of the disparate costly products called "tweaks"... Some are good but i cannot afford them anyway...My goal was to create myself my own products and give to others the motivation to do so, it is simple, fun and takes only time no big money and they worked for me then why not....

Then before judging , experiment and try.... Dont wait for scientific explanation they dont always exist and if they exist they are not always known by most anyway....

When you own the right electronic component after a well done study of all reviews the only guide are no more the electronic engineer or the marketting, it is your own ears with which you will reach the destination...

My best to all....
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...
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....
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....
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....😎
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....





Mahgister,
Since you were so right about this the first time, today I ordered Shungite plates and Herkimer crystals for my SG’s.
Remember to buy copper tape for the external side of the shungite small plate ( i use mini shungite plate for phone protection from Russia) it is what i called "golden plate" in my thread....

I use the big "golden plates" to controls the level of noise in my house electrical grid also....It is the main device for my electrical embedding control....Ratio quality control/price is very good compared to the competition.... 😊

Accounting for the actual state of your audio system by listening experiments, you can also use tourmaline, it will work differently than Herkimer diamond ( a kind of powerful quartz) and even some other stones like banded agate etc....It is a way to balanced the audible effect to reach the more naturalness of timbre perception possible....But if you begins the best thing is balancing golden plate with Herkimer or tourmaline....
As for how it works, its EM not acoustic.
I think it is the 2, the EM field modify the acoustical setting of the room and not only the physiology of perception...But your remark about the brain waves and the range of resonance of the S.G. seems very truthful to me and a relatively recognized fact...But it is not only like i said that the S.G. are affecting the human physiology but the room acoustic also because if you put on the S. G. a shungite plate or a quartz the effect are very different....And these changes are not pick by the brain directly but through the acoustical changed properties of the room....Then the S. G. change the physiology of perception but the acoustical space also....


Keep in mind that mine work in an interconneted grid with very thin copper cable, connected also to a varied grid of resonators of different size and different materials on the main caps, these materials (shungite and quartz or tourmaline) modify the audible effect in opposite direction, for example, amongst other effects, compressive or decompressive action with a positive or a negative impact...Balancing shungite and quartz gives the best timbre perception....

the modified and interconnected S.G. then does not change only imaging and soundstage but also timbre perception.... And timbre is not undertood in term only of pure frequencies but with other factors linked to the acoustical setttings of the room ( the spectral enveloppe  but also the time enveloppe)....

The general impact of my grids is so great that there is absolutely no relation between my audio system S.Q. before and after....


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....
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.....
In my room even these toys gives me audible positive effects, i improve them by connecting them in a grid and using my "golden plate" on them...

Your post remind me of those who speak about acoustic treatment using many thousand dollars of materials... I use homemade no cost materials, homemade absorber, diffuser, reflectors, and resonators, and at the end i succeed to have top audio experience for peanuts...

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.... Your ears will dictate the road to take one day at a time....

Simple....
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....
