"The total is more than the sum of its parts – and these are already of premium quality in the Lehmannaudio Linear SE."


Highest quality standards in features and design

For our production we use top-grade components without exception, which we buy from selected manufacturers. Thus our Linear SE mk II is equipped off the shelf with capacitors from Mundorf in the power supply and also in the signal path, an ahp fuse and Mogami cables. Vibration-absorbing SSC feet are another standard feature of the Linear SE mk II.

This reference class headphone amplifier also copes with the highest of aesthetic demands. The housing developed by product designer Guido Gutenstein will impress you with its simple elegance and a noble silk flat aluminium finish. Match different housing and faceplate versions with freely selectable LED colours and black or silver 3S Device Feet, as you desire. That way the Linear SE mk II will become your very personal gem to assort well with your taste and/or existing devices.

Some thousand music lovers in the world are already sold on our Linear headphone amplifier. Even with extremely demanding industrial customers – from the WDR to Sennheiser and Zimmerli – it has become firmly established. HiFi and studio magazine editors use our sound master as reference device. Now the Linear SE mk II is writing a new chapter of this success story.

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.

"We had expected that, owing to its potent output stage, it would not only consort better with the Sennheiser than its rival in terms of coarse dynamics, but also with the magnetostatic model from HiFi Man. However, the fact that it was playing the music with the same ardour, drawing the confines of the room by no means tighter, did surprise us after all."

"The Lehmannaudio Linear SE is a superb sounding and reasonably equipped headphone amplifier which can even double as a single source preamp if need be. Without neglecting even the smallest of details, this amp’s nonchalant style of play can instantly win you over."
