* Loads marked "est." are derived from the published voltage ceiling at a lower-impedance load
(V = √(P·R) → P_higher = V²/R_higher). All derivations are upward only.
Manufacturer-rated: 2300 mW @ 32 Ω (The Headphone List review spec table, THD+N<0.1%), 280 mW @ 300 Ω (multiple sources). 600 Ω derived from 300 Ω voltage ceiling. Output impedance <0.1 Ω from manufacturer.
