Stein Harmonizer's

Great information Audiotroy!
Thank you for sharing.
$4k for 4 is a lot more palatable than $3k each.

Makes me wonder how these and the ADD Sorcer4 would stack up against the PPT The Gate?

Would they all contribute to the SQ or might they be at odds with each other.

There is one thing for sure... Just when you thought your journey may have ended up pops a new contender!

OP your testing methdology mirrors our own, you take them physically out of the space and watch the system sound much more ordinary.

We also use Shakti Hollographs and Acoustic System Resonators as well. 

Uberwaltz all of these products are complimentary. 

We have also use the Audio Magic power conditioners best ever tested which also have a field generator in their conditioners.

We freaked out the designer of Waterfall Audio when we did the New York audio show and proceeded to unbox our Steins and Acoustic System Resonators and did the demo with and without them, his jaw was on the floor as he was compleatly incredulous that these kinds of producs would work. 

Shakespere summed it up perfectly there are more things in Heaven and Earth then in our phlosophy.  

These products should be pure fantasy except things like shuman resonance have been all proven, to be real, with products like the Stein's we have no idea how Mr. Stein came up with his idea but they really do work. 

We have so much more to discover why these devices work but they do.

That’s my favorite line from dealers and reviewers, by the way. 🤗 Although in fairness the Stereo Times reviewer explained it very well IIRC. Or maybe it was Positive Feedback. 

“So for the doubters yes they work why exactly is the mystery but without a shadow of a doubt too many people have heard them work and work well.”

Do they work with the QRT, Audio Magic, and Bybee products? I saw a Stein Harmonizer set for sale for an excellent price that I missed out on, but I wouldn't want to potentially buy something that would potentially interfere with other products since I cannot recall what principal the Harmonizers are trying to work on and it they'd throw off the effects of the other products which all seem to work under  the same principal among themselves.

SteinMusic Harmonizers explained (from the Positive Feedback Review)

Holger is interested in resonances—resonances on many levels… in wire, in components, and in the air. Holger designs and manufactures various items to 'manipulate' or 'control' or 'mitigate' these resonances so that our music is more engaging… or simply put, more fun. He also makes a line of electronics and sources… way cool. 

With the Harmonizers, Holger wanted to treat the air so that the music being produced by the speakers is, well, better. That is, that it can travel or move easier through the air making what we hear 'better'. How do the Harmonizers do this? The following explanation originally appeared in the StereoTimes review of the Steinmusic Harmonizer system by Mike Silverton and works quite well enough thank-you:

"The air molecules in the listening room are propelled through the loudspeaker and thus transmit the sound. In order to elongate the air molecules from their rest position it is necessary to spend energy. It is easier to move them once they're in motion. This phenomenon is similar to static and dynamic friction.

"To move a large rock is not an easy task. But once in motion it's more easily pushed forward. The Stein Music Harmonizer works on a similar principle at an ethereal level. The air, which is not actually moved, is charged with information, producing the same effect. It is elongated from its rest position without much effort and is thus able to transport sound of a different quality. This is a working hypothesis. While it does not claim to be complete or even understandable, it's the sound that counts.

"With little understanding of the science behind the phenomenon, often times audiophiles take for granted that the sound waves we call music simply arrive at our ears. Neither sound nor electricity can travel in a vacuum. It is easy to forget that sound waves travel by riding the molecules that comprise our atmosphere, the very air we breathe. This atmosphere is actually a variable mixture that conducts sound waves as well as electricity. It can be dry or humid, fresh or polluted, just to mention several states.

"The air in the listening room differs from the ocean's atmosphere or that of the mountains. It feels different and has different qualities, which brings us to its ability to transfer sonic information. Air as a base for transferring audio can be distorted by influences such as electric charges (electro-smog) from all kinds of electrical products, e.g., heaters, air conditioners and of course audio equipment. Air that does not get exchanged feels stale compared to outdoor air.
