Ever since Lehmannaudio turned the "emergency exit" of classic hi-fi amplifiers into a gateway to a new perception of music with the Linear in 2004, sonically frustrating headphone outputs have been a thing of the past. The Linear D in its latest mk II version now shows that things can get even better: its latest-generation digital-to-analog converter and its fundamentally upgraded analog circuit board open up entirely new horizons for listening to your favorite music—goosebumps guaranteed.

"You can sense the potential from the very first bars; the music is reproduced with enormous clarity."
— Hifi & Records

Comfort and performance

The Linear D mk II is the perfect complement to streamers and CD players. It detects digital signals, automatically selects the optimal input, and does away with the need for an input selector switch. The ESS Sabre DAC, mounted on a four-layer circuit board optimized against RF interference, features one digital S/PDIF and one TOSLINK input each. Low-loss mica capacitors on the main board and in the converter's analog filter, as well as ultra-fast amplifier stages on the converter board, guarantee reference quality in impulse reproduction. The revised low-Z copper analog board offers a completely new dynamic. With three gain settings, the Linear D mk II adapts to a wide variety of headphone and sound source combinations, and with two digital inputs and one analog input, it also proves breathtakingly expressive as a streaming preamplifier for active speakers.

The Linear D mk II brings happiness to those who want to enjoy music intensively and undistorted, and it brings people together who share the enjoyment of music: two parallel outputs on the discrete Class A transistor output stages powerfully drive two headphones of the same impedance without compromising the listening experience. 3S device feet decouple the Linear D mk II from the surface and ensure tranquility. This makes the Linear D mk II sound even more vivid now: rich, never intrusive bass, filigree resolution, and weightless elegance across the entire frequency spectrum. Turn the solid, damped potentiometer of the Linear D mk II. Rediscover your analog and digital music treasures!
