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.
Can someone post a link to the $10 amazon ones? I can only find more expense versions. Thanks!
I'm still lost. No one has provided any explanation. Just MC being a dickhead and mahgister talking nonsense. I guess this thread and this resonator are not for someone who would ever question things.
