Product Description

The Lehmann Audio Linear D takes the performance and convenience of your digital sources to the next level.

New and Improved

Lehmann Audio’s Linear headphone amplifier solved the problem of inferior headphone outputs, turning the “makeshift output” of any given amplifier into a gate to another perception. Taking this award winning analogue design and combining it with a state of the art high resolution Sabre audio DAC by ESS sets the ground work for a product designed to amaze listeners.


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 priorisation.

If no digital audio signal is detected the automatic input selector falls back to the analogue 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. Two parallel outputs on the legendary discrete solid-state class-A output stage simultaneously feed two headphones of identical impedance with supreme power without curtailing the listening experience.

The Perfect Partner

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.

Amazing Vitality

The Linear D will inspire your active loudspeakers to an amazing vitality serving as a preamplifier with two digital inputs and one analogue input. It’s also ideal if you just want to enjoy your favourite music up close without a flavour enhancer.

Just listen for yourself how shockingly 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.
