I have DC on my line plus about 8% distortion. I’ve tried multiple conditioners and DC blockers. All reduced dynamics in my system except for the following:
Emotiva CMX-2 DC Blocker and Line Filter
All of my sources and preamps are down stream of this unit. Amp is plugged into the wall. Tried PS Audio Humbuster, Furman, DYI and others. Also tried a PS Audio Premier regenerator upstream from my sources and preamp. I was neutral on this unit in the end as it did reduce the distortion but did not remove the DC. Also seemed expensive and did not notice a difference in sound.
