Lehmann Audio – Linear II – Headphone Amplifier & Pre-Amplifier
The Lehmann Audio Linear II is a reference-quality headphone amplifier and pre-amplifier engineered to elevate every detail of your listening experience. Handcrafted in Germany, the Linear II combines a dual-mono Class-A output stage with premium component selection to deliver exceptional clarity, dynamic precision, and a natural, highly transparent presentation. Its refined circuit design ensures a pure signal path with extremely low noise, making it an outstanding upgrade for critical listening, studio monitoring, and high-end headphone systems.
Designed to support a wide range of headphones, the Linear II features selectable gain settings of 0 dB, 10 dB, and 20 dB, allowing perfect optimization for high-sensitivity in-ear monitors as well as high-impedance full-size headphones up to 600 ohms. Two gold-plated Neutrik headphone outputs on the front panel allow either shared listening or convenient A/B headphone comparisons. When used as a pre-amplifier, the Linear II offers a clean, neutral analog output capable of driving active speakers, power amplifiers, and advanced desktop audio setups with exceptional control.
Every element of the Linear II is designed with audiophile-grade precision—from meticulously matched components to its noise-optimized internal layout.
