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 am using several Schumann Resonators in my system. The quality of the power supply and dc lead feeding the SR makes an enormous difference to the sound. I have experimented from a $25.00 wall wart linear power supply, to 12v battery powered, to the fabulous Paul Hynes SR5. The SQ difference between the wall wart to the SR5 is like comparing a lamp cord to Odin PC. The difference is that significant. SR placement can yield interesting results as well. I have tried; under speaker cables close to speaker binding post, under pre-amp, under IC from pre-amp, next to power conditioners. All these different positions of the SR will give different sonic effects. If you only have one SR, my favourite spot is on the front wall between the speakers about 8’ off the floor. YMMV
Thanks for the input. Will try your recommendations and let you know the outcome. The wall wart I'm using is a generic adjustable one that comes with switchable end connectors of various type. The resonator is a middle of the road model ($75) with larger 16V, 10,000uf caps. Looks like I may have to pick up a better power supply.
If you must use a wall wart for power, try to find one that is a linear power supply.
Tried mine in the areas suggested with no changes, except when my wife asked if it was going to stay up there on the wall between the speakers. I guess I'm just one who doesn't hear it. Will probably sell it at a loss monetarily, but as a gain inquisitively.
