The Lehmann Audio Linear SE is a headphone amplifier that closely matches the Linear D in power and specification but uses a different chassis. It is the larger and heavier of the two Linear series models, both placed higher than the small Drachenfels in Lehmann's catalogue.

Key specs that matter

Maximum output is 400 mW per channel into 60 ohms and 200 mW into 300 ohms. Four gain settings are available, at 0, 10, 18 and 20 dB. The rated bandwidth stretches from 10 Hz to 35 kHz at -3 dB. Distortion is under 0.001% at 1V RMS into 300 ohms, while the S/N figure is better than 100 dB. Output impedance is 5 ohms for the headphone jack and 60 ohms for the pre-out.

Engineering and use context

The Linear SE measures 120 x 296 x 59 mm and weighs 2.2 kg. Like the Linear D, it has a pre-out in addition to the headphone output.

Pairing

The selectable gain lets the amplifier drive efficient and less sensitive headphones alike without an external attenuator.

Alternatives

The Linear D shares an almost identical specification in a lighter chassis.
