I have had them installed in my system for a few weeks now. Even with the clean power of a PS Audio Power Plant running my system, I could immediately notice a lower noise floor, with dynamic and clarity improvements.
I have become a firm believer that anything you can do to reduce noise in the system will reap musical rewards. I should also add that I have always liked AudioPrism's accessories and have owned an AudioPrism Debut II amp and Mantissa Preamp for years. The company offers real products, not smoke and mirrors. The Ground Controls are easy to install and immediately hear. Try them; I think you will like them!
