First it was the Creek Evo 100A amplifier.
Recently, I bought a Matrix Audio Mini-i Pro 3. For the moment, it is on my desk, plugged into the wall, and buzzing while in standby mode. I had headphones plugged in, but even with no headphones or sources, it buzzes.
- I tried other outlets (with nothing plugged into the device other than AC... no speakers or sources).
- I tried an iFi gizmo (AC iPurifier and Groundhog +) but it made no difference.
- I tried an Emotiva line filter (CMX-2) and that made an immediate difference, but it was short-lived. I think I was just good timing the first time I plugged it in.
