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.

Does anyone have experience with the "Wizard" unit? What does it do and how does it perform in comparison to Electraclears, Symphony Pro, and Sorcer units? What are the dimensions of it?
@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.)!
@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! 
Well son of a...I wish I would have gone for the Wizard when I had the chance. Oh well, maybe in the new year I’ll be ready to get one.

Thanks bemused!
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.
