The Linear Pro has been designed as the 'professional' version of the popular, award-winning Linear headphone amplifier. This new version is carefully manufactured in small quantities, like all Lehmann products, and is designed specifically to be attached to professional audio gear. You can use nearly all dynamic headphones that are currently available on the market, and the carefully selected components and highly sophisticated circuit design guarantee a very high level of audio reproduction.

What makes this model 'pro' is the use of high-quality Neutrik XLR connectors for audio input. This keeps the Linear Pro fully-balanced throughout, helping add towards a complete, 'true' soundstage that will astound any serious headphone listener.

The broad frequency range of the Linear Pro means every audio detail is realised in the sound reproduction, and the switchable gain means almost any pair of headphones can be driven with ease. The two headphone outputs mean two people can listen to the same music at the same time.

Though designed for pro applications, the Linear Pro is also great for hi-fi enthusiasts who have high-end sources that include balanced outputs.
