The Arya is bright, but it’s not that far away from Harman. I do a little bit of EQ in Roon, but it never bothered me in movies etc. if you are looking for soundstage and improvement over HD650, the Arya or HD800S are obvious recommendations. The XS seems like a great deal though.Try to buy second hand or b stock (directly from Hifiman shop) Hifiman HE1000v2 (notice V2 not SE)
Very good tuning out of the box. Very close to Harman.
Soundstage and spatial effects are amazing. In my opinion much much better (in terms of tuning) than Arya or he1000se.
They are not harsh on top as Arya. Spatial effects are on the same level. Arya was unlistenable to me way too harsh with female vocals. He1000v2 only occasionally gets harsh but it's very minor.
I only changed from he1000v2 to Stealth as they were even better tuned and clear sounding.
I‘m obviously biased as Arya owner, but I enjoy them a lot and have zero urge to upgrade.
