Thank you all for your headphone-comfort thoughts. It is funny - to a certain extent, I would compromise sound quality just to be able to wear the things without discomfort. It would be really nice if I didn't have to compromise too much.
I tend to like a warmer sound - the pre-fazor LCD-2's are very close to my ideal, but the weight and the fit can be punishing. I tried the Sennheiser 800's and the treble response was a bit too much for me - though I agree that they were more comfortable than average.
I have a local dealer - Goodwin's High End - who are Hifiman dealers, and claim to have the Arya to audition. So, I think I will go see them and try them on. The trouble is that I need to sit there for at least 30 minutes to see how the fit works over time. I hope they have a sense of humor about that...
You also brought up some brands I knew existed, but didn't know anything else about, like Dan Clark and iBasso. I will start my auditions soon.
I really appreciate the opinions. I find it helpful, as I usually do on this site.
