Already since 2004 the Linear has made all common headphones to shine at their very best. Extremely demanding users rely on our top model from the West German Broadcasting Corporation to the audiophile TACET label to Sennheiser’s and AKG’s headphone experts. It’s not without reason that the Linear belongs to the reference class in its genre.

When you put on your headphones and load your favourite CD the Linear will give rise to wonderful worlds before your mind’s eye. Physical punchy lows and a delicate resolution reveal your favourite tracks in all their glory over the entire frequency bandwidth. Carefully selected components and an extremely sophisticated circuit design establish the foundation of our number on.

"The best we've come across."

— What Hi-Fi

A universal champion

With three gain settings it gives you an impressive listening pleasure keeping an eye on your needs anytime – and this using a vast array of headphones on the most diverse sound sources. In this context we have of course taken into account the varying performance requirements and sensitivity levels of the headphone types currently available on the market.

If you would like to share your joy at this quality of music reproduction with family and friends our multiple test winner will be happy to feed two headphones at the same time. Of course the listening enjoyment will remain equally fabulous then. The two parallel outputs of the discrete class A solid-state output stage provide the basis of this double musical enjoyment.

A propos: if you wish so the Linear will also stimulate your active speakers to a stunning vitality. In every situation a magnificent sound always striving for perfection – such is our Linear.



The Linear is available with three faceplate finishes.

Available upgrade options for the Linear

Order form

Upgrade for the analogue board

The new Linear II mainboard is equipped with the improved components of the Linear SE board and built using a special low-impedance technology (low-Z copper) which raises the price of the naked PCBs by a factor of about 10. But the effort is worthwhile. This technology results in even better dynamic values but above all it produces once again a significant increase of the sonic performance: transient response and spatial imaging are even closer to the original.

“You haven’t promised too much. As a lover of classical music with ample concert experience I can say that the depth graduation three-dimensionality instrument locatability and dynamics have clearly improved. Really big fun when listening to ’new‘ old records you have known for ages!“

"The damn pre-amp section is so good!"

Hifi News

"The Linear may look unprepossessing but it’s a very fine headphone amplifier indeed. It measures well and delivers unusually clear insight into the ‘how?’ and ‘why?’ aspects of music making not just the ‘what?’."

What Hifi?

"Feed in a good recording – Eric Bibb’s Good Stuff say – and it will deliver a natural and informative sound. And it is detail obsessive digging up a huge amount and arranging it into a cohesive and convincing whole."

TNT Audio

"Of all the companies out there manufacturing hi-fi it was probably Lehmann who was the first to really make a reputation and ultimately a business by becoming well known almost entirely through the internet."
