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.

Okay, I saw no reason why not to try this tweak.  I ordered two from Amazon.  I chose a $40 model simply for aesthetics.  I have been going back and forth both with vinyl and hi-res streaming.  I probably should not post after 1 hour of listening and 2 glasses of wine but I truly do feel these things are making the music more defined.  The instruments with them seem more focused and the subtle sounds pop more.  I suppose the real test will be when I can arrange a friend to come over to control their power and see what I say then!  This takes me back 20 years when I added my cold-air intake to my Integra GSR.....it felt like about 7 Hp on the butt dyno.  There's an expression we should implement into the audiophile world.  Our listening butt dyno.....love it!
Very good to hear, dhite. Mine will take longer to arrive but I'm never in a hurry. If they improve sleep or audio, it's a win. If not, so what; nothing lost that mattered. 

I'm smiling at your GSR reference. First new car was '87 Int.LX and I kept it 29 years and loved driving it every mile. Can't forget how impressed BMW 318 owner friend was at everything it offered, especially fit & finish.

Even without the required proof, my mind can accept the minimal science (so far) behind the SR concept, and also that perhaps mankind does not know everything about everything yet...   I'll wait and listen!
I'm glad you are a music addict because truth be told it didn't have an effect on my sleep.  ...for me its value is in the improvement in sound.  By the way, my 318 must have been built by the midnight shift...it was awful for me....only my Alfa was worse
I sleep like a rock (my wife doesn't and hates me for it :-)
I want those darn things for my stereo first!
Better sleepy-time for my spouse would be a nice bonus.
  (Just don't make me choose one benefit!)

My wife just said to me get those damn things out of our room.  I need a decent sleep.  A happy wife is a happy life so I am moving them to see if there is any sound improvement tomorrow.
