Here’s a third recommendation for HiFiMan’s big head designs—in my case, the HE 1000. They LOOK massive and awkward, but they’re exquisitely comfortable, very open-sounding (and sound-permeable: others can hear you, and you will hear ambient sounds in the environment), really deep and natural bass, extremely "fast" (those nanometer membranes, I guess) and transparent...I’ve owned a lot of headphones over more than 50 years, including STAX, and this will be my endgame pair. Of course, there’s a cost—namely, cost! They’re ridiculously expensive. I’m guessing the Arya are similar in comfort at least (very likely in SQ as well; I got my HE1000s from a friend in the biz; would never have spent so much on headphones otherwise).
FWIW, I also love the Headroom headphone amp. It eats batteries, but the cross channel processing circuit is a very subtle wonder. You know that feeling when one channel goes out while wearing headphones? Like your head suddenly got cleaved in two, or your hearing went out completely on one side? With the Headroom circuit engaged, disconnecting one channel sounds much more like what it would sound like with speakers: you lose one channel, yes, but you still have a sense of three dimensional space. This effect contributes to the realism of headphone listening in a magical way.
