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.

Regarding positioning, I think this is so system, component setup, rack/console, power outlet / power line dependant that I will simply advise to test placement and positioning for yourself.

My unit was inside the wood console (i.e. covered) initially. All my components sit in open areas of the same console or on the floor in front. Moving the Sorcer X4 to the top of the console brought additional gains, which I categorize as subtle. I’ve chosen to keep it in this position (vs. inside the console).

Note: I used the same outlet for the above evaluations. It is a SR Blue Duplex with the other outlet feeding my SR PowerCell. In other words, I have not tried placement elsewhere in the power line.
Many thanks, David, for re-starting the thread.
I strongly believe that there is no accessory product out there that can improve the quality of musical sound to the degree to which the Sorcer does. It is truly remarkable!
I thought I had posted to this/the original thread, but now..it's not there.
@slaw   You had posted. I was on vacation and only saved the first few posts. My apologies to you and others. If you can remember those questions/posts please re-post.
