Can anyone answer that without snark or sarcasm? (yeah, I know, a tough ask on the internet.)
I cannot answer your question being in no way a scientist...i apologize for my inability to really help about an explanation...
I already described in this thread what i was doing with my S.G. grid ( i own 12)
all i know is that these does not degrade the sonic of my gear/room in any way at all... It is easy to verify for me each day.... I begin the day with none of them on...
In the afternoon reading near my desk i listen music in nearfield with 3 on or off.... the three most powerful S.G. are on my desk near the gear... 😊
In the evening in regular listening position i switch on all the grid of 12 which are distributed around me...
Great difference in the listening nearfield or in regular position which is relative to the number of S.G. on and off , i seach for an acoustic metaphor here, the music is more easily floating toward my ears with them than without them.... The effect is immediate if i switch them on and off, on and off....
What change the sound color though ( for the best) is what i put on the top of the Schuman Genetaror: shungite thin plate with copper on the external side and herkimer diamond on it....
The shuman generator make easier for the sound wave to be catch by the ears...The air between instrument is more sensible and the soundstage is more detailled...It is like the color of my natural sound is more detailed now...
I dont know of any rigorous scientific explanation...Nor for the S.G. itself, nor for the additive sound effect of the Shungite+copper and Herkimer diamond....
it is filtering and blocking EFI and RFI ? Probably.... But i guess in the dark....
the only thing i know for sure is it is not a placebo effect mainly....
I lost my only physicist friend...and his world-wide expertise was in electro magnetic field of the brain.. Too bad...
My best to you....
