Blue Circle Powerline Filter ~ I had this set up in my main listening room and every time we took it out we put it back in. If you are an audiophile and have exceptional hearing this filter does something subtle but detectable. My system consisted of twin McCormack DNA .5 power amplifiers vertically bi-amping Monitor Audio RS6 speakers using Audio Art speaker cables and Esoteric Audio interconnects. I used a Placette Audio RVC as my pre-amp...simply exquisite.
I am getting old now and have sold off the system to someone who can appreciate the incredible sound field it produced. The Placette and Blue Circle are all that remain.
I get a discount on shipping and will pass that on to the buyer. North America only please.
