Schumann Resonator

To be frank i dont understand a so much STRONG "irrational" reaction and bashing of a so fun and cheap experiment, an a rewarding one for many in the past, with even possible new discoveries if someone dare to experiment?

For sure some people can register no effect in their system and room and for them because of the many factors involving the different noise floor levels coming from mechanical, electrical and acoustical sources... And the discriminative hearing history of each listener being another one...

There exist only one answer to the rejection a priori : prejudices coming not from science but from "scientism" and from patent "sellers" habits here or owners of costly gear, who dont like the idea that audiophile experience may not be so costly at all...

Am i forgetting another reason?

The truth is simple tough, audiophile experience righfully implemented MAY cost peanuts.... Sorry for those who dont like the truth.


Acoustic is Queen in Sound and Music, not electronic design...It is only his useful mate for some kind of reproduction via Fourier method.... 😊 But learn by yourself that this Queen is hermaphrodite and does not need this mate at all cost....

Dont conflate the 2 .....The cost would be very high in all meaning of the words....

And dont believe only in science, like some in religion, learn it at your own level: experiment yourself the truth.....



«Man is greater than science because he dont conflate knowledge with understanding and understanding with truth»-Anonymus Smith

« Some "Science" is often only a fucking habit»-Groucho Marx

«Is it not only  a recipe?» -Chico Marx

By the way a simple experiment i made numerous time sometimes forgetting to put some part of my S.G. grid ON:

I disconnected few minutes ago 9 of my 12 S.G. : results: collapse of the " envelopment listener sphere" potential diameter to a very smaller or less powerful one... It is the way how the sound can be sitting in our face litterally and powerfully...It is not related to volume deafening listening by the way even if some minimal volume is required...

I decide to put them ON again... Results : Regaining immediately the listener envelopment sphere normal diameter and power...

You can conclude to "placebo", but it will be an easy erroneous conclusion, because placebo work for small borderline audible change, not for the perceptive collapse of the listener envelopment potential sphere, if you experience one to begins with and if you know what this concept acoustically means anyway to begins with....

It is not soundstage which is about the way sound go out of the space between speakers and the way each instruments is posit in 3 dimensions in perceived space...Envelopment listener  potential sphere diameter or power, is not the same experience nor the same concept...Imagine a voice coming immediately from your left ears but the speakers are in front of you? Or the same voice coming from the back of your head? And the speakers are in front of you....This is listener envelopment sphere,,, I gain it way better with my Helmholtz mechanical equalizer completed but i gain it mostly from my S.G. connected grid.... The two devices were necessary for my experience...

Most audio system are not enough rightfully set in the acoustical dimension of their room anyway to give to someone even one audible envelopment listener potential sphere experience.... Most people work hard to gain only a decent imaging and a decent soundstage and envelopment listener sphere come ONLY after imaging and sounstage are there already...It is with natural timbre perception very difficult to recreate but easy if we know how to deal with acoustic.... And in a small room it takes more than just balancing passive reflecting,absorbing and diffusing surface...It takes an activation and controls of the pressure zones which i did with my mechanical Helmholtz equalizer and in a less powerful way with my Ionizers...

 By the way this envelopment listerner potential sphere is also  linked to the original way the recording engineer put his microphones  and the type chosen  around or near the performers....Your are projected in the original performing space in an acoutically  translated way by your own room acoustical settings... It is a way more lively experience... 

Most people here dont even know what this envelopment listener potential  sphere is in a 2 speakers system experience....

Then for them calling my experience "placebo" reflect only the poor environment where they listen to....Or their lazy prejudices against a cheap experiment...Or their lack of acoustical experience in a small room...

Am i forgetting another reason?

Yes, there are some people who believe in science and physics and not voodoo.  There are people who are not gullible or naive and can realize when they are being conned.  Some people don't fall for the logical fallacy of "the appeal to authority", especially when the authority on science you are appealing to is Groucho Marx.

Results : Regaining immediately the listener envelopment sphere normal diameter and power... 

Interesting.  I thought the SR devices do not affect the sound or the listening environment, they only relax the listener so the music becomes more enjoyable.  Are you that easily affected that a change in mood can be turned on-off like a switch with immediate results?

Yes, there are some people who believe in science and physics and not voodoo.

Myself i trust science but i dont "believe" in science to begins with...It is not necessary to believe in something that is repeatable, i trust that it will be possible to repeat the experiment...It is not always the case, because of the indefinite numbers of factors at play, then believing here is the most sure way to be deceived by "science"... I will not go further...Scientists dont believe first and last in scientific law they prefer to test them daily and use them or trespass them ....There are limits to their test also and they try to go further....It is called history of science...

And like said someone more wise than you and me: «History of science is science» Goethe

The difference is i dont use my take on science for an alibi to my laziness or my curiosity in audio....I try to think without narrow mind with science but also with an open mind out of my limited understanding.... Most phenomena are anyway unexplained by science at all....Are you even conscious of that?

By the way before insulting me, learn how to read my COMPLETE post before interpreting it... There are 3 citations and only one from Groucho... Then put the 3 citations in your head and process the three together to understand what is the meaning intended by me about science...3 things simultaneously in your head are too much? Quit thinking about science and try sport... 😁😊

Interesting. I thought the SR devices do not affect the sound or the listening environment, they only relax the listener

Before answering a post it is better to read the context of the thread and the other posts of the poster you anwered to...

I even suggest a precise EXPERIMENT of my own, with repeatable results, demonstrating the opposite of what you think about this only "subjective relaxing" effect +a placebo effect....




And we are all happy to know that you are not like us a gullible one....You spare 20 dollars congratulations!

There are people who are not gullible or naive and can realize when they are being conned.

I have no noise in ANY system when I route everything correctly.. I don’t have inherent noise. If I did I would fix the piece of equipment.. Pretty simple for me.. My equipment doesn’t make NOISE it makes music... I quit having that problem 45 years ago..

Proper ROUTING, goes a long ways.. Be careful with cables... I move cables I pay.. simple.. 15-45 minutes. A warm up time always fixes mine.. A cable swap that's new, 24 hours, used a hour or two.. BUT the first 15 minutes more so than anything.. Pretty subtle after the first 24. TT cable use to drive me nuts.. The new din 5s.. RCAs are so much easier..
