Acoustic Revive RR-77, 777, 888 Schumann Generator

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?

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....
