Schumann Resonator

I got 2 of these from Amazon...careful that free returns are applicable.  I charged them up, turned them on and holy moly.....they do help with my system.   What I hear is between instruments, a definite difference in upright and electric bass, wider know...all the good stuff. At first I thought it might be increased brightness, but is still the same in that regard.  I still can't believe it, and will listen again tomorrow (saved the packaging for the return)...but today, I'm about to keep them.

I bought one several years ago when the Acoustic Revive rr-888 came out. It actually made me feel somewhat nauseous when I first started using it. I experimented with placement as well as using a linear power supply.
I have no idea how they actually work or why. I've read material about it as well as Jeff Day's (?) reviews-- I was still left ignorant of what it is actually doing- I think it affects the listener, but some people who I demo'd it to didn't notice a thing.
I still have it, and it is set up if I want to turn it on; I did find that it changed the sound or my perception of the sound, but I'm not sure that I actually preferred the result; it seemed to homogonize the sound and in some ways bring it "in" tighter, taking the raw edge off; but like power conditioners, I wondered if that more "raw" sound without it was providing me with more acoustic information, so I usually leave it off.
Height off the ground is a factor for sure.  FWIW, the thing draws so little current-- on the order of hundredths of an amp, at least in the case of the rr-888, I saw no need to continue using a linear supply. (The switching type supply might still interfere with the system so it is on the standard house lines, not the electrical subsystem dedicated to the audio system upstairs). 
There were some old threads here that had a lot of posts-- some people used multiple units and really like what it did. I think this is a case of subjective applied voodoo---
This is where Geoff Kaitt is sorely missed. He could explain it and add a quiz, plus tell us how it affects wormholes. Thankfully, I haven't encountered any rips in the fabric of reality when I used the one I bought. 
Miller- I'm actually a tolerant person. That's why I'm still posting here. 
The "dithering" analogy is as good an explanation as any and better than most. I don't think it is psychological, but I did find that some people didn't experience it or notice a difference. And I'm one who actually prefers my system without it, so I'm not inclined to view it through the lense of expectation bias. I mentioned Geoff only b/c he was always on the fringe with some wild stuff and meant it in a light-hearted way-- I had no issue with him, personally.
