I'm with you there, but man...$2000.
I still think you can't go wrong with a XS and something that has a decent EQ and simply be happy. If you sprung for an Arya O, more power to you. I'm sure they are very nice!
I bought Qudelix-5k and some velcro. My setup is XS->dual 2.5->balanced 3.5 input (for 2v) on Qudelix and generally use BT; sometimes not.
Used
these settings (which are a riff on Oratory's that are in AutoEQ, which has it's database built into and loadable on the Qudelix).
I don't know if you use something like that on your Arya, but I'd suggest it.
To me the sound signature is likely *very close* to what you see on these phones...Which I agree is pretty much what many people want (imo).
I seriously challenge someone to do *something* like that (maybe with an amp that uses a little more power than the Qudelix, at least at 1v) and not be fully happy.
It doesn't cost $2000 to have a very nice setup these days. Rather like $400. The XS are such a ridiculous steal that literally anyone and everyone should buy them just to try them, if nothing else.
If you feel the compulsion to upgrade phones after that (I *always* have before, and I don't...now focused on amps) I think you likely have a "problem" (which is also fine...People need to have a hobby).
