Using my Grado sr80 with the headamp in the high output I cant use more then first notch, otherwise its too loud. Theres also à clear supply-hum. In the low output its fine. Figured it was à gain high/low. But then I used s set of sennheiser HD580, and with those there was hardly and difference in sound between the two output. Is this how it should behave? I really would not think so myself... Source is the burson dac, so should not be too large input signal.
