Cost effective Schumann Resonator

After reading about the Acoustic Revive unit, I was looking on Ebay and found a Schumann Resonator for $175 (plus $20 for a very nice plexiglass case). It's model designation is Chartres Mk.2. It is made by a fellow named David in Indonesia. He was a pleasure to deal with, start to finish. The unit arrived in about 10 days. The fit and finish was reassuring. It is a circuit board with good quality components mounted between two sheets of well cut and finished plexiglass.
I have read, and failed to understand a lot that has been written about Schumann resonators, but I am willing to. Suspend disbelief and try a tweak that a lot of folks say works. My initial reaction on hooking up the resonator was disbelief. Sound stage and localization were noticeably better. I had to disconnect and reconnect the unit several times to convince myself that I wasn't fooling myself. Mechanism of action be hanged, it made a very positive difference in my system. This finding was confirmed my moving it to a second system where, again, spatial information seemed much improved.
I am very happy with this purchase. Results rule!

I also use and enjoy these Schumann frequency generators. As you pointed out positioning is a key to their being used with success. Too low in placement, and the sound is fuzzy with increased low frequencies. As the unit is elevated from the floor the focus and clarity improve. I have one between the speakers (my horn system), and one  behind the listener, both 
at a height of 6' 8" off the floor. Six inches of height change made all the difference between being an improvement versus just a change in sound.

I also have one installed inside the car - next to the interior ceiling and 1 foot behind the driver and passenger seats. Same effect- instruments have better focus. Confirmed by independent passengers who have no idea what I am turning on and off.

The ultimate version of this technology is the Synergistic Research Atmosphere Unit. It generates more than one frequency  and pulse duration.  This model is currently installed in my Terasonic speaker system, and allows you to synchronize the sound of each recording with the rooms acoustics. Adjusted easily using an I Pad as a remote control.

It allows each  recording to be heard at it's best. Expensive but to me, worth it.

Question for users: why do you think location, especially height is important when placing the Schumann device? It just seems odd, I'm not doubting it. You know, what with the wavelength of the Schumann wave being so long and all, 26,000 miles long.

While reading up on a new Clones music server I linked to their site and discovered that Funjoe has his version of a Schumann Resonator. He recommends a height of 5' and close placement to the listening position.

So I took out my Quantum version, which I've kept close to my system, in the rack, and placed it on a CD cabinet close to where I sit (about 1 yard) and it's 4' off the floor. What a difference it made. Much clearer presentation with better separation and a surprising increase in bass definition. There are real fingers plucking and pulling on those bass strings. It's really easy to hear the difference. Even the highs were better defined. There's a moment in a familiar recording where there's this shiny kind of shimmer, high up in the register, that turned out to be some very rapid high end piano key strokes, struck very softly. I can clearly hear piano foot pedals being engaged, sustained and released, when previously they just had a soft, thumpy impression of being used.

With the older placement, I heard only a slight improvement. Goes to show that I should keep up on things like this. Anyway, I was so impressed  that I went and ordered one from Clones Audio and it's even better than the Quantum unit. Much better. It has a slight buzz that you can hear with your ear close to it while the Quantum unit has a more aggressive buzz. Being a much older device, it might be on it's last legs.  The Clones device is also less than half the price of the Quantum unit, delivered from China. 

I put the older unit in my bedroom to see if there's any benefit and if there is, then there's going to be another Clones unit to order.

All the best,

I found one on Amazon Prime for $70, I could not resist the temptation.  I will report back my findings.

Innocent questions: (1) Since the wavelength of an electromagnetic wave at the Schumann frequency of 7.8 Hz is equal to the circumference of the Earth 🌎 how can they fit a 25,000 mile long antenna into that little box? And (2) how can the Schumann frequency wave even fit into the room?
