I'm shocked by the quality of genuine chargers too. No line filters to speak of. I had one of the ethernet over powerline things and there was loud noise in my headphones on any transmission. Now I always add one or two snap on Ferrites on any mac charger. On both sides, for good measure. Totally kills off any powerline noise.
