At one time I had 18 of them. Now I have none. There is little question that you can hear their impact. If I carefully avoided all signal wires and focused on transformers, I could hear some improvement in signal to noise. If I got anywhere near the signal, however, they robbed the dynamics from the music, much like most ac filters do. I sold most long ago and must have sold the few remaining about a year ago when I found them in a box.
I suspect that a revealing system is harmed by them. Someone has recently said that they include quartz. Perhaps they do, but they do not sound like it.
