Expert Audio Engineering Commentary

Tonal Profile

DUNU is the exception in this segment: it prints both scales and they agree. 107 dB/mW at 16 Ω converts to 124.96 dB/V, and the sheet says 125. Nothing has to be inferred, and nothing can be misread.

Gain Staging Advice

125 dB/V means full scale on almost any source is far past safe listening. The useful range sits in the bottom quarter of the dial, which is exactly where cheap volume controls have channel imbalance.
