Lehmann Audio Drachenfels
With the introduction of the Linear in 2004, Lehmannaudio raised the sound quality of headphone amplifiers to a new level. The Drachenfels now represents a new generation of headphone amps: our champion with an entry-level price tag scores with leading-edge technology and, owing to its modular options, can be matched to ever new situations. With regard to sound it’s particularly the tremendous wealth of detail that strikes the ear, together with a perfect control of what’s going on. Even in the thickest musical hurly-burly the structure remains discernible at any time and every detail clear-cut.
Analogue? Digital? Drachenfels!
The modular design with cutting-edge components opens long-term perspectives for quality-minded music lovers who have demands on sustainability. No matter if streaming via WLAN or ethernet, linking Bluetooth sources or conventional digital players – owing to modular pc boards, which are available at short notice, the Drachenfels gives the right answer to all of these requirements. Even with the advent of new digital standards, a simple swapping of both module and rear panel will enable an upgrade!
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 power switch located on the front reduces the power consumption in standby mode to an eco-friendly value of less than 1 W. Moreover, its space-saving dimensions offer you plenty of placing options for the Drachenfels. Use it as a headphone amplifier or preamp and discover the happiness of intense music listening.
- Drachenfels D The Drachenfels D complements the detailed, light-footed sound of the analogue model by a digital-analogue converter of the latest generation. The Sabre DAC from ESS on the quad-layer circuit board, which is optimised against RF interference, offers both digital S/PDIF and TOSLINK inputs. Low-loss mica caps on the mainboard and in the analogue filter of the converter as well as ultra fast amplifier stages on the converter board guarantee reference quality in transient reproduction. Enjoy your digital musical treasures from a streamer or CD player in full Lehmannaudio quality!

Lehmann Audio Drachenfels
Compact yet revealing, the Lehmann Audio Drachenfels packs transparent, neutral playback into a tiny desktop chassis. Its sound favors clarity and balance, with taut bass, articulate midrange and clean, extended treble that preserves transient detail and imaging. Reviewers at Fidelity Magazine praised its confident neutrality and long-term musical performance when driving full-size headphones. The Drachenfels pairs studio-grade parts — gold-plated Neutrik headphone outputs and an ALPS volume control — with a low-noise analogue path, delivering lively dynamics and reliable resolution. Beyond a headphone amp it functions as a flexible preamp and, thanks to a modular design, can accept optional Wi‑Fi, Ethernet or Bluetooth boards. For listeners seeking a compact, well-built desktop amp with professional pedigree, the Drachenfels offers a compelling blend of sonic poise and futureproofing.
Pros
- Very neutral, detailed presentation with strong transient response and imaging that suits long listening sessions and full-size headphones.
- High-quality mechanical construction—gold-plated Neutrik headphone outputs and an ALPS potentiometer deliver a tactile, durable desktop experience.
- Modular connectivity and flexible use cases: acts as a headphone amp and preamp, with optional Wi‑Fi, Ethernet and Bluetooth boards to expand functionality.

Cons
- Measured SNR (>85 dB) and noise-floor performance may leave a slight hiss with very sensitive in-ear monitors.
- Network and wireless features require optional module purchases—these capabilities are not included out of the box.
Sound Quality
90/100
The unit 'deals with fast sound events reliably' and renders tones cleanly without exaggeration, which supports very good transient response and micro-dynamics. The review's praise when driven with the Amiron Home and NightOwl suggests it retains liveliness and punch with demanding tracks.
Noise Floor
78/100
The review does not call out an ultra-quiet or 'black background' performance; the spec lists SNR >85 dB (gain 0 dB), which is respectable but not reference-level for very sensitive IEMs. Given no explicit praise for dead silence and the SNR figure, the noise floor should be considered quiet for most full-size headphones but may show slight hiss with very sensitive IEMs.
Headphone Compatibility
84/100
Measured outputs (110 mW @ 330 Ω, 180 mW @ 33 Ω) and a phones output impedance of 5 Ω make it well suited to drive a wide range of over-ear headphones; Fidelity tested it with Beyerdynamic Amiron Home and AudioQuest NightOwl with excellent results. The 5 Ω output impedance is fine for most full-size headphones but not ideal for multi-driver low-impedance IEMs (<1 Ω), so compatibility is very good but not universally ideal.
Build Quality
92/100
Fidelity highlights high-quality parts: gold-plated Neutrik headphone sockets and an ALPS potentiometer with a smooth, solid feel, indicating premium mechanical choices. The tactile impression of the volume control and robust outputs point to excellent overall construction for desktop use.
Features Connectivity
83/100
Out of the box it offers RCA line in, a pre-out and two Neutrik headphone outputs, which is above the bare minimum and adds useful flexibility (multiple headphone outputs and pre-out). The review emphasizes a modular platform that can accept optional boards (Wi‑Fi, Ethernet, Bluetooth), which raises its practical expandability even if those modules are optional rather than standard.
Value for Money
89/100
Fidelity positions the Drachenfels as 'priced at about €500' and describes it as more than just a headphone amplifier for demanding home use, implying a justified premium for its build, sonic performance and modularity. That language supports a 'worth it' / justified premium assessment in its class.
