looking that on my laptop, 45% is -11.8db(I changed the unit with a right clic like a boss ^_^)
now switching from 1X to 3.3X that's about +10.4db. you see where I'm going here?
@jseaber while trying to look for some specs on the revB in case lehoang was somehow reaching the limits with the K612. after all that thing seems a little horrible to drive, worst than an audeze http://www.innerfidelity.com/images/AKGK612.pdf I noticed that on the rev B combo dac/amp you still give the same power output with different loads as nwavguy(for 33 and 150ohm at least), except that the default gain values are now different.
I'm very aware that you're doing epiphany's customer service when you try to help here, but because you're always so reliable, we now count on you for everything ^_^.
oh well, akg writes: Max. Input Power 200 mW on the specs of the k612... does that mean the headphone summons armageddon in a wild explosion after we pass 115db with it? @lehoang15tuoi how about selling that headphone? that would solve a bunch of problems. (ok I know the way out, I'm leaving now... bubye..)
