Description of the Linear from the official Lehmann Audio website:

The next stage of the successful Linear headphone amplifier sets new benchmarks as to sound quality and the direct musical experience.

For those who have been dealing with headphones, our headphone amplifier by the name of Linear is a household name. The Linear has already enchanted thousands of music lovers all over the world and is also a constant with the most demanding industrial customers. From the WDR Studios to Sennnheiser headphones to the Galaxy Studios, from Audiamus to Zimmerli the Linear is highly valued and the reference unit in tests for hi-fi and studio magazines worldwide.

Dynamic headphones are much more different than most people realize. For the same sound pressure level the power needed with different headphone models can vary up to a factor of about 500! Impedances can be different to a factor of more than 20!

This is the reason why different headphone models have very individual requirements to the headphone amplifier driving them in terms of voltage and current. Everybody who once has connected a high quality headphone to any given standard headphone output knows about this problem.

“In my opinion, the Linear belongs to the reference class of its kind. It creates a relaxed, open, neutral and detailed acoustic image.”
