Give them time to play in and loosen up. IME, they get a little more natural if not quite to the level of the 800s. Notice I didn't say "burn in", haha.
Don't worry, I'll leave the lid firmly on that can of worms. But, I will also definitely be giving the Arya a great deal more listening time. If nothing else, I always find my brain and ears need some time to adjust to new headphones. Plus, they sound phenomenal as is, so whatever psychological, physical, or metaphysical forces are at work will have plenty of time to make their adjustments.
