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.

Having moved my two devices right behind my speakers I did do the A/B test with my spouse in the room.  For my small investment of $28 i figured why not try.  We listened to 4 artists to conduct this test:
Pat Metheny - Guitar Jazz
Mt Joy - Younger Days - Indie Rock
Alabama Shakes - Rock / Soul
Al DiMeola - Jazz Guitar Fusion

All songs were played at the same volume level.  We played them all the way through and then plugged in the Resonator and then went back and played back to back.

Now I need to place in a major caveat.  I am tweaked out already.  I have 18 Synergistic Research HFT's, Synergistic Orange Fuses and Outlets and a Inakustic 3500P PC.  I have Perfect Path Technologies, EMATS in my Electric panel, fuse box, under all of my electronics and I have pasted all my electrical plugs with PPT graphite.  In addition, my system with no turntable is well over $100k.  Please don't take this as bragging because it is not.  I just wanted to set the stage for my simple outcome, which led to a further discussion with my wife.  

Simply put, we struggled to hear any difference.  However, the one thing that we agreed on is that the sound stage may have been a little bit larger.  But it was so minute.

So will i leave them plugged in.  Why not.  It did not degrade the sound, but I can't say it really helped either.  

So the question I throw out if you bothered to read my lengthy comments is....is there a law of diminishing returns for these tweaks?  I already have a ton of tweaks already.  I hate to say this but the best tweak I have used in my system has been the upgraded SR orange fuses.  Does the quality of your components matter?  In other words, do you think this SR would work better for someone who had say a $5k system more than someone who has a $60+ system.  I wonder.  

I guess the only way to answer these questions is to take all of my tweaks out and start one by one putting them back in to see where the biggest improvement came from.  Unfortunately I am functionally blind so I have to rely on my hearing.  At this point I love my music and don't have the time nor desire to do that extensive testing.

So, the bottom line....for me the SR was not really impactful; however, everyone has a different system and for 10-20 bucks it is worth the experimentation.  



That's the spirit. That is what I have always done. Every single thing I have was tested. First for proof of concept, then gradually more and more as and if it continues to work. If not, adios MF! 😂😂

Disappointed there wasn't a better result. Sounds like there was, just not as much as we were expecting. Then again, only $20! Do you have a cat? They seem to love em. Krissy's goes and curls up to hers all the time!

Try my little experiment.... Put on the capacitors of the S.G. a thin plate of shungite for phone at few bucks each and a bit of copper tape on the external side after that add an herkimer diamond 3 or 4 gram... Another under 20 bucks that perhaps will surprise you.... But with all the tweaks you already have i am not surprised by the result...

Try my litlle experiment....For fun.... 😊

The sound will be different in the three cases, with shungite on top or with herkimer diamond or with the 2 together... We learn something doing that very strange on the audible effect of minerals in an electrical field....for sure some will call you "nut" here....

But you have already lost it for them....

My best to you....
