For more clarity I use the Schuman Generators in a non conventional way, I use a passive (passive: non electrically linked to the audio system) multiple cabled connections from the S.G. to my powered battery stones grid around the listening room... Then I use the S.G. like a stone and crystals enhancer, the effect is so great that cheap 13 dollars usb powered S.G. have an impact unbeknown by most...
People usually use way more powerful costly S.G. with linear power supply,(costly) and feel some improvement... I feel the same amazing change with my cheap S.G. and perhaps more...
Then the S.G. is a guenine audiophile component but way more potent then usually admitted when used with crystals and stones linked by cable to a battery powered grid... For example i have cabled stones even in my speakers. :)
The S.G. is the center of my stones powered grid and his emitted frequency plays also all along the cable connecting the stone placed near it or on top of it to the grid(without touching the embedded antenna of the S.G.tough) ... I know nobody who has experimented with these kind of stones battery cabled powered grid...
(a remark: the grid except for batteries is passive, non linked to the audio system, the stones are near the gear, the connectors, around the room, that's all. the batteries with magnets are only there to "dynamise" and activate the crystals)
A note: I feel the effect not only in nearfield, but also on normal distance hearing from the speakers, and also surprisingly for me in the headphones...
