Yes, and back then I was certainly wrong at the start in thinking it should be blocked - then came comments on the resonator devices and I had to realize it’s of course beneficial to have it, and even amplify it.
Now, I think that holding a steady resonance in the listening room will still be affected by local changes in the Earth’s Schumann resonances. If these devices monitored the local activity and compensated to keep it even in the room, might be even better. Possibly.
(Just noticed an abundance of “if”, “could”, “might”, “possibly”, “maybe”, etc, when perusing my writing… It is certainly a possibility that I might possibly be an idealist, if that’s the right word, could be.)
