ADD-Powr by Coherence Systems --- Power Conditioning Products


Recent research into power conditioning approaches and products brought ADD-Powr to my attention. This company, and it’s products, were previously unknown to me.

The company, Coherence Systems, is based in Santa Monica, CA. and has been in business for some time.

An introduction and general overview can be found within their ’About Us’ page: https://add-powr.com/about

Nordost (in 2008) purchased the QRT technology that these folks developed.

Bill Stierhout is the proprietor / owner and the brains behind the ADD-Powr product line.

Several days ago, I installed the ElectraClear device in my main audio system.  I gave it an hour of time to adjust  and then removed it, listened and reinstalled it.  My friend said they substantially improved his sound quality.  An interesting tweak for $75.  

I removed the ElectraClear, listened and reinstalled the ElectraClear.   The music is clearer and smoother.  Unbelievable.   After several days, I still cannot believe this small $75 ElectraClear device can make such an improvement.  It seems there is electrical magic going on in this box.  The music simply has more air, is clearer and sounds less congested.  BTW, my 2-channels home theatre system also sounds better.  I purchased 2 ElectraClear devices, one for each system.

Hello david_ten -!

Here is the video link that I failed to post on 9/23/19

It's a good sample of how the Sorcer X4 performed under a spur of the moment demo video at last year's RMAF.

At the least, the ADD-Powr Wizard harmonic resonator will add a level sonic clarity never thought possible.

I  think that the Sorcer X4 is not intended to transform the listener as much as it is intended to transform your power source. But I can say that
the sound is greatly harmonically transformed, simply by adding altering the AC line. Music never sounded so good!
