Expert Audio Engineering Commentary

Tonal Profile

112 dB/mW at 40 Ohms is the highest sensitivity in this batch by five decibels — 110 dB from roughly 0.05 V. The practical consequence is the opposite of the usual worry: with an open 50 mm dynamic this efficient, a noisy output stage is audible as hiss between tracks, and a high-output desktop amplifier will spend its life in the bottom eighth of the volume pot.
