Schumann Resonator

twoleftears,
Did you invest in one, or are you just being "funny?"

Stringreen,
I'm glad to hear that you have discovered this tweak (I hate to minimize it by calling it that) which is so affordable and effective. I started reading about it on these forums some years back, and then more or less forgot about it. I give Mahgister credit for making me aware of it again. It is so effective, and so cheap, it just doesn't make any sense not to try it!
I use two, and would not be without them.

Since I’m certain that a few members already consider me a tweaky wacko for using and endorsing Schumann resonators, I will reinforce that view by stating that I took Mahgister’s advice, and placed the shungite plates and the Herkimer diamonds (a type of quartz crystal) on top of each resonator a couple of months ago, and yes, they do change the sound. Without the crystal, in my system, it was better defined but too dry. With the crystal, just right.

Why are so many members obsessed with HOW it works? It works, and that is all you need to know, aside from the fact that almost anyone with a roof over their head can afford it. 
I'm sure that there are some members who already consider me a tweaky wacko for using one, and I would like to reinforce that belief by adding that I also took Mahgister's advice concerning adding Shungite tile and Herkimer diamonds (a type of quartz crystal) to the resonator so months ago. Yes, it does have a positive effect on the sound. Shungite alone is more detailed but too dry. Withe the added crystal, it's just right.

I paid somewhat nore than the one that you reference from ebay a couple of yearers ago, and recently, one of the two suddenly died. I think I'll try one of these. Yes, they definitely work.
