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.

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?

Okay, I swear I read somewhere that people have been using them with their ElectraClear with power conditioner and heard great improvements. Not sure why mine behaving the opposite way.

anyways, both my wall receptacles are Hubbell with surge protection. I’ve plugged in each of the ElectraClear with Furman and Panamax on two separate outlets. Still can’t hear a difference. May be I have to listen to them in this settings for a while and then do a negative test and see if hear a difference.....good or bad. 
But thanks for the suggestion.
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.
