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.

I'm placing an order today for a Wizard and have ordered 3 more ElectraClears after having one in my system late last week. I've had similar components to ozzy and when I saw he had success with an X4 I thought of giving Add-Powr a try. David_ten turned me on to Stealth usb cables so I figured his judgement on Add-Powr to be good as well so I'm looking forward to seeing and hearing how more Add-Powr products perform.
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.
On one of the outlets on my power conditioner I doubled up on using an ElectraClear to good effect. Similar to how I would add HF mc-0.5’s at the wall outlet. I got another ElectraClear coming that I will double up on another outlet where my dac is plugged and see how that goes. For the price of these ElectraClears they are a bargain.

Yes, i have an ElectraClear plugged in where both my modem and router is and I definitely got not only an increase in clarity and presence on my stereo but also my tv picture where I stream movies from my Apple TV. 

How would you rate the increase performance of the Symphony Pro versus an ElectraClear?
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!
