OK first off the spelling is Shumann. It appears several rags have given awards for the Acoustic revive resonator. 6 Moons, Stero times and others. It appears the device projects a resonance of 7.83 Hz. Which is said to be the resonance of the Earth and life. Adjusting and settleing of magnetic fieldsaround us. Improves the viscosity of the air. Eliminates standing waves. It also has a calming affect to us humans. Allowing us to relax an get into the music. We all know how moods affect our listening experience. It is also said that it affects the moleccular structure of our cells in a good way.. No wonder everyone is a bit nuts nowadays. I used to blame it on the digital age with all the EMI, RFI, MIcro waves out there. Maybe I was right all along . Who knew. The science is that the earths frequency of 7.83 Hz is being thrown off by the offending RFI, EMI all around us, creating a bit of havoc with our Karma and well being. HMMMMMM!
Scientifically it makes a lot of sense. Recording studios, music schools use the device to good affect. The price is a bit high for what it is but the affect IMO is worth a try.
Now the Ion generator is a DIFFERENT device than the Shumann Resonator. I will state that when I'm in the listening room nowadays it is just a more relaxing experience. It also appears to clear the air and allow the music to flow through the air as a veil was lifted. There is more of a live feeling to the music. It is the clarity of it all that has taken me. The inflections of the real sound that makes your brain think it is live. You know what I mean.
This is NOT my imagination or fan boy recco. Even my Wife the non audiophile of the year Queen noticed a difference for the good. " The voice is so clear its errie" " I was starteled when the music came on when I went to do the laundry, I thought there wassomeone in the basment" OK I'm in. My wife rarely makes a comment on the sound. Last time was I got the Pipedreams. Anyway the music sounds better to us. Even its a placebo the music is better.
