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 Steirhout is the proprietor and the brains behind the ADD-Powr product line.

The product line is listed here: https://add-powr.com/products

Based upon what I'm reading...placement issues...given my system configuration, I think I'm better off pursuing (my) current path. Enjoyed the reading.
@david_ten ,

I read you blog the other day and enjoyed it. When I started introducing the Bybee iQSEs, the High Fidelity Cable Mc-05s, and the Akiko Audio Triple AC Enhancer & Phono Enhancer into my all analog system, I had very similar sonic experiences and the effect is cumulative. Looking forward to a comparison to the Corelli.
The product really interests me even though, for the cost I'd expect a higher quality looking casing.
Thanks for the information. I currently use some Akiko Audio products and am very impressed.
