* 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.
Topping A90 SE output per multiple reviews citing manufacturer spec: 2000 mW @ 32 Ω (some sources say 3000 — using conservative 2000 mW), 250 mW @ 300 Ω. Balanced output is ~4× higher. 600 Ω derived from 300 Ω. · Source ↗
Planar driver note

Planar-magnetic headphones can have high current demands that are not fully captured by the power headroom model. Even with adequate headroom, some solid-state amps may struggle to deliver sufficient peak current for transient dynamics. Prefer amps rated for low-impedance planars.
