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 clarity....space between instruments, a definite difference in upright and electric bass, wider soundstage...you know...all the good stuff. At first I thought it might be increased brightness, but no....it 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.

So what was the final blind test tally for these things?

I’ve only heard positives anecdotally, which is fine for those that are happy with them, and the only blind test I’ve heard told me they did nothing to the sound in a legit blind test. He hasn’t posted here, preferring to stay out of the fray.

He’s been very honest in the past with his many tweaks and has been mostly positive with the acoustic, vibration and electric improvements to his system, although some were very subtle.

My experience is similar to his. I would be tempted to try these things if I could hear of any positive blind tests, which should be quite easy to perform. Otherwise, I prefer to try things based on audio impact, not medical with audio being an unscientific byproduct.

Anybody, Bueller, anyone???
