Lehmann Audio
Lehmannaudio Vertriebs GmbH was founded in 1988 by the young student of audio engineering, Norbert Lehmann, in Cologne, Germany. Since the summer of 2007 their place of business has been Bergisch Gladbach. With a passion for detail, Lehmann have been producing products which are now world renowned for their sonic quality.
During Lehmann’s audio engineering studies, they were listening to two amplifiers with identical technical specifications in a direct A/B comparison. They found it was really amazing how much they differed in sound quality: one delivered sound, the other one music. There they realised for the first time that good sound depends on much more than technical data such as power, distortion factor and signal-to-noise ratio.
That listening session sparked a passion in Lehmann which has never ceased

Taking the award winning analog Design of the classic Lehmannaudio Linear headphone amp and combining it with a state of the art high resolution Sabre audio DAC by ESS of the newest generation is already off for a very good start. Additionally this DAC module with its complex and noise performance optimised four layer board utilises two digital inputs (Toslink + SPDIF) and features automatic input sensing with Toslink prioritisation. If no digital audio signal is detected the automatic input selector falls back to the analog input. For all this no input selector is needed.

The solid ground for this experience in the Lehmann style is provided by selected components and a sophisticated circuit design. Three optional gain settings allow an impressive listening pleasure with the most diverse headphones on the most diverse sound sources. The Linear D will inspire your active loudspeakers to an amazing vitality, if you so wish, serving as a preamplifier with two digital inputs and one analog input - more than many people need.

But probably you just want to enjoy your favourite music – up close and without flavour enhancer. In this case the Linear D will conjure up a happy smile on your face. What‘s more: two parallel outputs on the legendary discrete solid-state class-A output stage will simultaneously feed two headphones of identical impedance with sovereign power without curtailing the listening experience.

The Linear D auto-recognises an incoming digital audio data stream and switches to the internal high performance ESS Sabre DAC that can handle digital input formats up to 24Bit/192kHz. Which makes it a perfect partner for your streamer and upgrades your optical drive or any other digital source with optical or SPDIF output!

Just listen for yourself how impressively three-dimensional the Linear D outlines an aural stage: with physical, deep lows, a filigree resolution and a downright weightless elegance over the entire acoustic frequency spectrum.
