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!

All things considered, I want to try it.

RW: Thank you very much for the kind words. I think there is at least one alternative that has appeared only in the last month or so from Alan Maher designs (AMd or Alan P Maher on his facebook store). I don't yet know all that much about how it works except that it shunts environmental EMI/RFI to ground. A wallwart sized plug-in for an open outlet and you start with one plugged into each of the 4 corners of your home. Called the "Quad Cell Antenna" - cost: $40 ea. Haven't tried it yet, but I probably will early next year. User comments have also included the reduction in the amount of ringing in the ears...as well as reduction of pressure in the head or sinuses immediately upon plug in, for some. Alan, apart from designing a very wide (sometimes bewilderingly so) array of noise reduction products for AV use, is also an allergy sufferer and has learned for himself how to design all his products with that angle in mind. It should be pointed out though that Alan has done a lot more examination into the health ramifications with EMI/RFI than I and says (as is on his site in posts as recently as yesterday) that EMI/RFI poisoning is linked to increased risks of cancer (which he goes a bit into). He also specifically deals with the Schumann Resonator, as do some of the users who've used both it and the QC Antenna. The QC Antenna has an AV range of about every 10 feet or so in the area near the system and a range of about every 250-300 sq ft for health benefits. But, that should at least be a start for anyone looking to boost AV performance - and reduce health risks from environmental EMI/RFI....except for Nonoise, for whom it's apparently too late... ;)

I use 6 Schumann devices in my listening room. 4 units are about 6 feet off the ground and the other 2 units are about 2 feet off the ground. The effect on SQ is very noticeable. A big improvement.

After reading this, I've looked into them a bit. What difference is there between a $38 unit versus a more expensive one, say the $175 one, besides just the cost? Does the higher priced one work better than the lower priced one in a larger room because it has more power? I guess I have more reading to do to.

Abucktwoeighty,

Acoustic Revive cost a lot more than that. Do you have a link for a $38 Schumannn?
