New Arya owner here. I got an used v2 unit this week which, according to the previous owner, may not be fully burned in.
Between this and the ADX5000, my current favourite open back, the jury is still out, I definitely need more time. Thus far the ADX5000 comes across a bit warmer (having a bit more mid bass) and the Arya more dynamic. So ADX5000 has a bit of a Cadillac feeling while the Arya reminds me more of a top level BMW.
What surprised me the most ofvthe Arya is that is driven to very satisfactory level by my Hiby R6 Pro DAP in balanced mode : not at its best, obviously, but with very good results, certainly more satisfactory than the Audio Technica.
I am very happy to acknowledge that the Arya does not sound "distant" as tge HD800 I once owned did. The Arya got it right, and so did tge ADX5000: I still can tell which does best, including insyrument separation and layering.
Other than that, I am using the Arya unbalanced with my Violectric V200 and balanced with am Xduoo TA-20: thus far I favour the latter. The ADX5000 also gets along very well with my SMSL SH-9, while the Arya sounds clearly worse.
I also have an Ananda and a K812 and especially the latter puts up a very good fight for the crown of the only one I will keep among these 4: it is more sibilant than the others but it does not bother me much as I am a treblehead (and 50 y/o). The soundstage of the K812 remains among the best even in 2021.
