Arya Organic wins on value and driveability with 16 Ohm impedance and 2023 planar tech versus the HD 800 S 300 Ohm dynamic design. The HD 800 S delivers superior soundstage per its Ring Radiator specs but at higher cost and power needs. Both remain current per grounded facts with Arya at $1299 MSRP and HD 800 S at $1699.
