LehmannaudioDrachenfels 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.
