Lehmannaudio Drachenfels Headphone Amplifier
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.
