Product Summary
The Lehmann Audio Drachenfels is a compact headphone amplifier and preamplifier designed for listeners who want a serious upgrade over the headphone output of a typical DAC, amplifier or computer, but in a much smaller and more flexible chassis than many traditional high-end headphone amps.
What makes the Drachenfels especially appealing is the way it keeps things simple without feeling basic. Lehmann Audio has focused on a low-noise analogue circuit, a high-quality ALPS Blue Velvet volume control and a practical fixed-gain design that works well with a wide range of headphones, making it an excellent choice for everyday high-quality private listening.
The Drachenfels is also built to fit naturally into modern systems. It can be used purely as a headphone amplifier, but it also works as a compact preamplifier, making it a strong option for customers using active speakers or building a neat desktop or small-space hi-fi setup. It is an excellent choice for anyone wanting compact size, serious sound quality and useful system flexibility in one elegant unit.
