The Linear SE is a headphone amplifier from Lehmann Audio, closely matched to the Linear D in power and specification with a different chassis.
Position in line
It is the larger and heavier of the two models in Lehmann Audio's Linear series, which sits above the compact Drachenfels entry model.
Key specs that matter
Maximum power is 400 mW into 60 ohms. Gain is switchable across 0, 10, 18 and 20 dB. Distortion is under 0.001% at 1V RMS into 300 ohms. Signal-to-noise exceeds 100 dB. Power, gain and distortion figures match the Linear D. At 120 x 296 x 59 mm and 2.2 kg it is heavier than the Linear D.
Pairing
The switchable gain settings suit both efficient and less sensitive headphones without an external attenuator.
Alternatives
The Linear D shares near-identical specification in a lighter chassis.
