The Drachenfels is a compact headphone amplifier from Lehmann Audio. Lehmann Audio is a German manufacturer specialising in headphone amplifiers, and the Drachenfels is its most compact and accessible current model.
Position in line
It is the entry point in Lehmann Audio's current headphone amplifier lineup, considerably more compact and lighter than the Linear series and without its additional power and switchable gain.
Key specs that matter
Maximum power is 180 mW into 33 ohms, dropping to 110 mW into 330 ohms. Rated bandwidth is 10 Hz to 35 kHz. Gain is 12 dBu. Distortion is under 0.006% at 1V RMS into 300 ohms. Signal-to-noise exceeds 85 dB. At 160 x 120 x 43 mm and 0.5 kg it is a compact, light unit for a desk with limited space.
Pairing
The modest power output suits efficient dynamic-driver headphones rather than demanding planar magnetic designs.
Alternatives
The Linear D and Linear SE sit above this model in Lehmann Audio's headphone amplifier range with substantially more power and switchable gain settings.
