Headphones amplifiers — Lehmann Audio Drachenfels

The Drachenfels is a compact headphone amplifier from Lehmann Audio, built with a modest but well-specified power output. Lehmann Audio is a German manufacturer with a serious reputation specifically within the headphone amplifier category, and the Drachenfels represents the brand's most compact and accessible current model.

Position in line

It sits below the Linear D and Linear SE in Lehmann Audio's headphone amplifier range, considerably more compact and lighter than either of those two closely specified models. As the entry point in Lehmann Audio's current lineup, the Drachenfels trades some of the Linear series' additional power and switchable gain flexibility for a pocketable, desk-friendly chassis.

Key specs that matter

Maximum power is 180 mW into 33 ohms, dropping to 110 mW into 330 ohms - modest figures well suited to efficient headphones rather than power-hungry planar magnetic designs. 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, practical for a desk with limited space.

Sound and use context

Expect a clean, modest-power presentation suited to efficient headphones rather than power-hungry planar magnetic designs - Lehmann Audio's reputation within the headphone amplifier category rests on delivering transparent, low-coloration amplification rather than an overtly voiced or characterful sound, and the Drachenfels should reflect that same underlying design brief at its accessible entry tier.

Pairing

The modest power output suits efficient dynamic-driver headphones rather than demanding planar magnetic designs, so checking a specific headphone's sensitivity and impedance against these modest power figures is worth doing before assuming universal compatibility.

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, worth the step up if a specific headphone demands more current than this compact entry model can comfortably provide. A dealer or online comparison against the Linear D and Linear SE is worth doing before purchase, since the added power and switchable gain those models offer may prove useful if headphone choices change over time. Cable quality between source and this amplifier matters less than confirming the specific headphone gain requirements fall comfortably within this modest amplifier power ceiling.
