OK,
I seem to have gotten off on a wrong foot with Alan here. Let's get on track here. I have a specific situation and wanted some answers. The answer may be buried in the long AC thread but I don't want to dig through it.
I use an APS Purepower 2000 regenerator. I am quite happy with it but recently I ran into a ground loop hum issue. I thought a regenerator would be immune to it but it apparently is not. I solved the situation by going to balanced interconnects, but I know there is a potential difference somewhere on my power distribution. I am trying to see if any of your filters can be used in conjunction with a regenerator to combat this issue.
For me to buy something to try, I have to be convinced that the methodology is credible to me. So far, I am still trying to understand....
