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.

Many thanks, David, for re-starting the thread.
I strongly believe that there is no accessory product out there that can improve the quality of musical sound to the degree to which the Sorcer does. It is truly remarkable!
Here is a video with Bill of Coherence Systems at RMAF.
It is an ADD-Powr Sorcer A/B demo.
The listening test was done at the neighboring booth, Zavalinka Records from Russia.
Nikolail and Maria of Zavalinka had a reel tape recording of classical guitar. 
The AC power is shared by all of the booths.
I hear a discernible difference and improvement, when the Sorcer is active.
Worth checking out.

Indeed, the ElectraClears are an amazing bargain. I have several distributed around my system and home, and there is a fullness and dynamism to the sound that is quite satisfying, whether the source is digital or analog, Even the OLED picture shows a startling improvement.
Even the wi-fi appears to be faster! Does anyone else notice the improvement to your computer image or wi-fi?

Also, the Symphony Pro adds another level of sonic tonic!
@yoby : The Wizard does what the Sorcer does but just not with as much "in your face" attention or urgency. It makes the presentation more relaxed and smoother. Placed near the digital or pre-amp front end is the best location. It extracts detail and nuance that is buried in the digital signal. Amazing!
It is a modest 13 x 11.5 x 1.5".
It gives more of what the Sym Pro and Electra Clear are doing - harmonizing / tuning the system (with the antenna coils I suspect) plus inserting harmonics onto the AC line in such a way as to resonate the entire music signal. Sort of like a real time tone control but without any of the phasing artifacts! 
@t_ramey    Sorry for the delay to reply.
Question: So you think that the ElectraClear is improving the performance of your computer, i.e. speed? Maybe that would also account for an improved image and streaming experience?
If the processor speed increases then ....whoa! wow! certainly stop the presses news! Eh?
The Symphony Pro definitely does a fine thing to improve tonality in the music - night and day increase in transparency, as well as big time increase in the sound stage. ElectraClear has a nice warnth and fullness, ala tube, plus it creates a fullness to the sound. Yes, punchy, articulate, solid, dimensional. Carity and presence also improved. 
i can continue with more adjectives, so I'll stop.
Together they are a no brainer -
I even hear a wonderful improvement to the radio in a Panasonic boom box, driving a pair of small Dyne audio speakers used in the RS Optimus line (from a long time ago.)!
They are available at Tweek Geek. Perhaps you can get a little discount there.
Or, contact Bill at Coherence to see if he has any B stock deals.

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!
Hello david_ten -!

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

https://www.youtube.com/watch?v=MA2G0UbecFU&app=desktop

It's a good sample of how the Sorcer X4 performed under a spur of the moment demo video at last year's RMAF.
Indeed. I have a Wizard in my system and it performs quite amazingly in my system. The music presentation is greatly improved, harmonically enriched. It is an amazing product as there is nothing like it. Harmonic resonance through the AC line.
That offer is a great inducement with a complete 30 day money back policy. 
@debjit_g
  Has anyone used ADD-Powr products with PS Audio latest re-generators, like the P12, P15 or P20 ?
I am using the X4 with the P3. The X4 must be plugged into a wall outlet and NOT into the P3. Doing the latter will be an utter degrade - the sound is harsh and high frequency glare. Installing X4 directly, unimpeded into the wall outlet on the same circuit is a HUGE change!
Stunningly beautiful sound is the result.
Therefore, with the ADD-POWR technology in parallel to, or precedes, the PS regenerator, then very good things happen. Very compatible! 

For such a novel product to be conferred Brutus Award 2021 honors is no small feat.
