Amp/DAC suggestions needed for Hifiman Arya

[AlmostFinishe]

Currently running a JDS Atom + Topping E30.
Though I’m well into the territory of diminishing returns/$, I’m hoping for some suggestions - Is there anything to gain from a hardware change with these headphones? E.g. would a THX / other balanced amp cause these cans to become overly analytical/sibilant?
Primarily interested in amp advice, though DAC suggestions are also welcome.
Budget is up to ~800 USD. If there’s a product/stack that is considered by Arya owners to be worth the extra cost, I'd consider it.

If the maximum volume is already loud enough (which I presume it is), then no, there is nothing more to audibly gain from a hardware change with those headphones (there could be with software e.g. PEQ though). Your stack is already transparent within the limits of audibility.

Arya are hungrys headphones. I would say that the balanced out of A50S would be the minimal to get most of it, the A90 would be the ideal.
