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.

They are similar outside of the transformers/coils and number of "QRT" units. This affects the conditioning of the power the units receive, and ultimately the sound. Bill's original QRT units could be tuned by cleaning the power it was fed with power conditioners and power cords, and this seems to be similarly true with these new units.
I have been accumulating ElectraClears the past month and am really impressed with what they are doing. I was going to get a Wizard but am going to wait and save for a Sorcer down the line. I’ve got ElectraClears in all the outlets in my music room and in the tv room. I just recently started putting one here and there into my CPT 1800 conditioner where all my equipment is plugged in and have gotten excellent results with one in the same receptacle as my dac as well as power supplies for various components.

Yesterday I plugged one in next to the power cable that goes to my modem and have increased clarity and musicality as I stream all my music. These ElectraClears are working in conjunction with PPT Omega mats and cards to great effect. I used to have 17 each of the HF mc-0.5’s but the wife didn’t like the look of so many magnets sticking out of the outlets and they didn’t mesh well with the PPT stuff and they didn’t work well when plugged directly in the power conditioners. These ElectraClears work great in every location I’ve tried so far and bring a detail and clarity along with musicality I have not had before. I’m jealous right now of you Sorcer owners but these ElectraClears are keeping me satisfied until I can get a Sorcer of my own some day.
@sadono I have a Quad that is on a dedicated breaker. The Quad consists of a SR Blue Duplex and a SR Black Duplex.

The Corelli and my SR Active Grounding Block SE utilize the Black outlets.

The Sorcer X4 and the SR PowerCell utilize the Blue outlets.

The UberBUSS is connected to one of the outlets in the SR PowerCell.
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.
