Lehmann Audio Linear D MKII

Lehmannaudio Linear II

The legendary headphone amplifier, redefined

The Linear II is the logical evolution of the award-winning Linear – a reference headphone amplifier that has set global standards since 2004. In the second generation, Lehmannaudio takes the proven sound quality to a new level, offering audiophile music lovers even greater transparency, dynamics, and control.

Unadulterated sound reproduction – confident and lively

The Linear II offers the highest level of naturalness and musical detail. Its powerful Class A output stage ensures powerful, artifact-free reproduction of even complex musical pieces. The combination of Low-Z copper technology, Mundorf capacitors, and vibration-damping 3S feet creates optimal conditions for fatigue-free, intensive listening – even over extended periods.

Versatile

Not only an excellent headphone amplifier for up to two headphones, but also a high-quality preamplifier for active speakers or power amplifiers, the Linear II impresses with its sonic superiority. With selectable gain levels, it can be flexibly adapted to different sources and headphone impedances.
