The comfort does get alot better through usage, I was complaining all the time at first, but now it's quite normal, and I can assume they'll get yet better before settling.
I just got my first amp, the Porta Corda MKIII, and despite many people claiming it was less responsive to amping, and was very forgiving, I already love the sound even more. Of course, higher grade phones, such as my old ATH-AD900s, sound understandable better, and I can barely wait to amp my Audio-Technicas coming in a few weeks.
