I apologize for not responding sooner Charles.
I’m the individual who had luck with that specific line filter. In my case I was getting noise injected directly into my ADA1250-5s. No inputs plugged into them, just connected to the speakers.
It would appear that I have crappy wiring in my home and am getting DC noise injected across all electrical circuits, regardless of whether they are dedicated or not. The DC offset did the trick.
Daisy chaining two together actually ended up working best in my environment.
Hope that gives you more context and happy to answer any additional questions.
