I have a general question regarding the powering of inefficient headphones. This may not be the best place to ask it, but since i am an HE-4 owner, i figure its close enough.
Anyway, i have been powering my HE-4 with a Burson HA-160. It gets me to listening volumes at a little past 9 o'clock, and i am happy with the sound quality. But does this mean i am powering the headphone correctly? More specifically, does getting my HE-4 to listening volumes without cranking my amp mean that i am providing the headphone with adequate power?
