Freemand, I have to withdraw my earlier observations. Last night I was listening and noticed that my music had lost its life and pace. It was boring, undynamic, lacking in ambience, with a one note bass. I kept trying to figure out what had gone wrong and could not conceive of what it might be.
While preparing for bed it hit me--the ERS that I put on my breaker panel. First thing this morning I listened again to the last cd I had played. Afterwards, I removed the ERS and relistened. Bingo! The life was back! This is all consistent with my previous experiences with the ERS, but I don't know why I initially got favorable results. Since the panel is on the other side of my house, perhaps the initial impact is favorable but ultimately gets to the system. I really don't know, but my ERS goes back into the closet.
