Schumann Resonator

Never respond on these forums, but do use lot of tweaks.
Near-live main system, will keep up with Raidho 35K speakers when testing same cd at Axpona (at least on clean cds),
Projector based home theater system, good to very good, but not great

figured should reply for mapman and others
Bought AR-888 few years ago, demo, so trial from MD, the large online seller. Curious due to positive reviews, and to date the most expensive tweak ever bought.  Had DirectTV then and tried out ARROW show. Put the AR-888 on a cabinet (maybe 4 feet up) at back of room. Was shocked to hear much more details in the sound of the show. Turned out ARROW was far more complicated mix than I thought. Also turns out it helps the picture quality. Have tested on 2001 movie (pretty clean bluray, not grainy like 2010). Can see more 3-dimensional image and more vivid colors. Is definitely more pleasing to watch with AR-888 on. Whenever I have tested it, can usually tell improved sound and picture quality.

Do not use on main system. Have tried and was better separation of images. But heavily boosted the bass. Small room and had to turn down sub too much and I like the sub effect. If can counter that, may use AR-888 someday again. Not hard to move if want.

Is strange and not sure why works. Low frequency EM signal, doable if look at half price Indonesian Chartes V (wish knew about that one to save money) due to electronic trace circling inside around and around to get large EM wave. Chartes V does show sine wave. Expensive ones claim to be more accurate. Not sure about cheap ones; tend to like trial periods. Tempted to get a second like Chartes V sometime, but read one review where tried 888 and previous model and person got nauseous. 
Again, perhaps the oddest tweak I have and not sure at all why works, but it does work. If you can get cheaper and still works, clearly that is best.
PS have even suspected it helped when listening to a quality DAP recently, but would have to keep testing that, since surprising

These devices don’t do anything for your audio gear or room, they make the person more in tune with the frequency of the earth.

Why not the 2 possibilities, an effect on the brain and a physical effect in the electrcal grid of the room?

If you read my post you will know that anyone can make an experiment i devised with the S.G. that is very objective with 3 possibilities and different coherent repeatable results:

 Shungite ( compression of the sound), Herkimer diamond (decompression of the sounds) and the 2 together (more balanced audible effect) on top of the S.G. caps...This prove a physical effect...

Is it not simple to do and to understand?

I started using SR's many years ago, at first a single up near ceiling, front wall, centered between speakers. Sound stage greater height but more recessed than without. Added second near ceiling, behind listening position, centered. This pulled sound stage forward and intensified solidity of center image. My SR's had potentiometer which varied intensity of these effects. I later added linear power supplies, thought I may have heard improvement, perhaps placebo effect here.

Over the years I tried various positions of both sr, sound stage always pulled towards position of sr. Near ceiling always best sq.
Over these years I periodically removed and inserted srs, always preferred sr in. However, as my system improved from various equipment changes, therefore, more dimensional imaging, larger sound stage, I found sr's to be detrimental. The pull of sound stage with sr's created a more artificial ss, center image always compressed, especially width. Without sr's, more natural proportion of width, height, depth of ss. I've not used my sr's for perhaps two year.
I never perceived any lowering of noise floor with sr, ss changes only effect I heard.

In thinking about these ss effects just now, I'm curious if four sr's could be superior to none. All centered near ceiling, front wall, behind listening position, two added on side walls. Decrease intensity and widen out center image. Not curious enough to try.

Overall, my experience was initial enthusiasm followed by slowly diminishing positive results. In the end, another failed tweak. Still, I can imagine sr's could be a positive in some systems and rooms, not a bad tweak by any means.

I can say the samething with my S.G.

I correct that by putting on them for a more balanced effect my "golden plate" (shungite plate+copper tape on the external side) + an Herkimer Diamond...

The effect is more natural with that than without.... Then what you experienced dont surprize me at all...

S.G. dont work at all on the noise floor of the house/room/ and gear...

But the unambiguous  perception the audible effects of the S.G.  ask for a minimally not too high noise floor... It is the reason why many people did not hear any audible effects.... The noise floor of a house filled with appliances, and in  an acoustically untreated room with gear with no mechanical vibrations controls means nothing coul be perceived of this subtle but very real effect....
