Drachenfels joins the Lehmannaudio range as an affordable headphone amplifier with premium specifications and a new modular design concept, suiting it to even the most demanding modern headphone users.

Operating as an analogue headphone amplifier, the Drachenfels offers 12dB of practice-oriented gain which, due to the smooth running ALPS Blue Velvet potentiometer with excellent synchronism and the ultra low-noise circuit, dispenses with the need for a gain switch. The advanced technical knowledge that has gone into the circuitry means that the sound performance offers a tremendous wealth of detail and pin-point timing, all captured within a highly engaging musical envelope.

However, where Drachenfels finds its niche is in its modular design. The back panel is designed to come away from the structure so more input options can be added with upgrade modules (available from late-2017), bringing with them more advanced features. The idea for the future is that even when new standards and listening preferences come to market, Drachenfels can be modified to suit rather than discarded and replaced.

The Drachenfels is built using the finest components available for the price. From the Neutrik headphone sockets to the low-loss MKP precision capacitors, the audio path is clear and unaffected by unnecessary devices. The clever design also allows it to be used either as a headphone amplifier with two outputs, or as a single-input pre-amp for a power amplifier or set of powered speakers. The small footprint makes placement in or near a system very easy, and operation is as simple as pushing the power switch and adjusting the volume dial.

When you buy Drachenfels, you are purchasing a high-quality analogue headphone amplifier. But more than that, you're opening up a gateway to future product developments, all of which can be added with an easy module upgrade, rather than needing to entirely replace your beloved headphone amplifier.
