Expert Audio Engineering Commentary

Headroom Notes

13.08 V and an input that tolerates 30 dBu - roughly 24 volts - before it clips. That input figure is the rarest number in this whole batch: almost nobody publishes it, and it is the one that answers 'will my hot DAC overload the amplifier'. With 30 dBu of headroom the answer is no, whatever you plug in.

Gain Staging Advice

Output impedance of 0.1 ohm and 16.5 dB of gain. The gain is the highest of the desktop amplifiers in this batch, so with sensitive in-ears expect to use very little of the volume range - Topping's own low-gain setting exists for that reason.
