* 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.
Schiit Magnius SE output: 2000 mW @ 32 Ω, 300 mW @ 300 Ω (both at 1% THD, per Schiit spec). Balanced output is substantially higher. 600 Ω derived from 300 Ω voltage ceiling. · Source ↗
