“The total is more than the sum of its parts – and these are already of premium quality in the Lehmannaudio Linear SE.” — i-fidelity.net

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.

HOUSING SURFACE FINISHES AVAILABLE – Silver (aluminum) and Black (aluminum)


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.
