Lehmann Audio Linear Headphone Amplifier - Ex-Demonstration

Product Summary

The Lehmann Audio Linear is a premium headphone amplifier designed for listeners who want a serious dedicated amp for high-quality headphone listening. Long regarded as one of Lehmann Audio’s key products, it is built for customers who want more control, refinement and musical transparency than the headphone output from a typical hi-fi component, DAC or computer can usually deliver.

What makes the Linear especially appealing is its straightforward, sound-first design. Rather than trying to add unnecessary extras, it focuses on high-quality analogue headphone amplification with carefully implemented circuitry, selectable gain and the ability to partner a very wide range of headphones. That makes it a strong choice whether you use easy-to-drive models or more demanding audiophile designs.

The Linear is also flexible enough to fit naturally into a wider hi-fi system. Alongside its twin headphone outputs, it includes a line output so it can also work in a broader preamp role in suitable setups. It is an excellent choice for customers who want a dedicated headphone amplifier that feels properly high-end, but still remains compact, elegant and easy to integrate.

This is an ex-demonstration unit in the Silver finish that has been very well cared for. It comes supplied with original boxing and accessories.
