Schumann Resonator

To my ears the resonator sounds as if it adds space to a system that is already wall to wall. This added space seems to come with a higher degree of focus and detail and with a more stable image all across the wall. The image seemed wider more stable and made me feel more at ease and relaxed..not stuck to my chair with my head in a vice.

Yup. And the more you use, the more of this you get. I'm at 10 and thinking might try a few more.  

Most all of these circuit boards have a tiny little trim pot. Probably fine-tunes the frequency, or but who knows? One of my fun projects, twist the trim pot and see if it makes any difference. Like these things aren't strange enough, tuning by ear. 

Ted definitely figured out something along these lines, he has an app where you can adjust soundstage width and depth and other stuff from your iPad.

I have been using Audiopoint inverted couplers, the  APCD4s for several years and with proper placement and the right tensioning I can extend the soundstage down a couple of long walls..To tight =s too bright.. back the tension off a touch and there you are. Or I can focus the center stage.  If you want it wrong keep adding more and it can sound like stretched pseudo surround sound..your choice you may like that sound. These can be threaded into mounted panels or use brass threaded inserts into materials and then thread the coupler and tune to your delight..Look at the overall shape and the center is inverted and will capture, focus and disperse energy or with another of our devices ground the resonant energy. Brass is the metal of music and Geometric shapes matter.
This method of usage with this specific product is something I have adapted for my own use.  I am a company member.   http://starsoundtechnologies.com/productsDetail.php?APCD4-Invert-38

Interesting...

 I created a cheap version of this already with connected by cable  brass chinese bowls  that help soundstage and focus...

 But this product is certainly better and not too costly thanks...

Maybe the addition of the Schumann resonator enhanced and further activated the previous sonic benefit that was provided solely by the Apcd4s. Tom

Buy bye.

Sorry, but this thread just does not resonate with me ...
