Yeah it's just my HD-650's needing so much power. I just tried out my Grado SR-80's with the DragonFly, and 50% is enough to be extremely loud.
I just ordered some HE-400's, and those are supposedly easier to drive than the 650's. So the combo should be just right for me.
Although I will say, even maxed out for my 650's, it sounds more than fine. :) This device is amazing!
