How much more detailed is the HiFiMAN Arya compared to the HD 600?

I'm looking to buy the either the Arya Organic, or the HE1000 Stealth as an upgrade to my HD 600.

Detail and resolution are things I value greatly in headphones, as tonal imbalances can be adjusted with EQ if necessary. And I am feeling some FOMO hearing people gush over these qualities with their Arya or HE1000.

There is nowhere near where I live that offers any high end headphones to test out in person.
