Well I'm coming from lower budget Sennie hd600 and Hifi-man he4xx. And was recommended to step it up a notch to the Arya stealth. Still on only a modi-magni stack. What do you think? Very pleased so far with the he-4xx, but lacks detail (which the hd600 has). Still my go-to cans for most things, the most comfortable wear-wise also listening. Any ideas? Also have akg k712's which are very brittle, need a lot of burning in, but looking to step it up a notch. Within the confines of my dac/amp setup. The arya stealth is three times as expensive of course, that's the absolute limit of what my wallet will tolerate. At around a grand usd. Then I think I've reached my peak dollar-wise of what I want to spend on hi-fi gear. Of course marginal increases in listening excellence, and not sure if my ears can hear the difference.
