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.

@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.

Another post highlighting the pairing / synergy between the Sorcer and SR. In this case with SR's power cables.

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.
