Expert Audio Engineering Commentary
Headroom Notes
Truthear publishes clean per-jack, per-gain voltages (1.4 / 2 Vrms single-ended, 2 / 4 Vrms balanced) and then two power figures — 150 mW at 32 ohms and 55 mW at 300 ohms — without saying which jack they belong to. The 300-ohm figure only fits the balanced output; the 32-ohm figure fits neither cleanly. Only the voltage is recorded here; the power figures are left out rather than guessed at.
