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.

Hello,
I just purchased 2 Electraclear and placed each of them in my Furman IT reference 20i power conditioner and a Panamax surge protector. Is that a good place for them?

And do these units have a capacity in terms of how much power is consumed in a particular system?

Thanks for the feedback.
ADD-Powr has a new upgraded version of the ElectraClear.  Its price has increased to $125 (from $75). 

I asked them what was upgraded and how does it compare to the older ElectraClear unit I already own.

Yes, I bought the new versions (soon to be discontinued) of ElectraClear.

I must say I’m not hearing anything positive rather negative impact to my system. It sounds a little dull or sluggish. As if it’s holding things back. Crispness is gone. Bass below 30 HZ seems to hang.

Since there’s no burn in period for this device I don’t think anything is going to change other than my ears getting used to them. What am I missing?

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. 
+1 for @yoby 's guidance.  Repeating what he said: NOT into the Furman and Panamax. Plug the Furman and Panamax into separate duplexes and the ADD-Powr units into the open socket of each duplex.
