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.

Hi srmahmud00: I've never been a fan of plugging one power conditioner into another. Try plugging an Electroclear and your Furman into the same duplex first. I would do the same with the Panamax. 
Hi uberwaltz: I use Perfect Path Tech omega mats, e-cards, paste, Stop Its, and The Gate in my system. I recently installed four Electraclears, one into the AC outlet right next to my main breaker box where I also have The Gate plugged in. The other three are plugged into three dedicated line outlets feeding my audio system. The Electraclears play very nicely with all of  the Perfect Path stuff. The sound is now more dynamic and punchy, as well as a little more articulate and detailed without harshness or edginess. I hope to explore the more sophisticated products that Bill has to offer in the future.
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?
