LINEAR SE

Reference-class headphone amplifier with Low-Z Copper circuit board technology, Mundorf capacitors and 3S absorber feet. The Linear SE is the audiophile-grade variant of Lehmannaudio's flagship headphone amplifier, featuring an upgraded component complement that elevates the already exceptional Linear to reference performance levels. Standard equipment includes Mundorf capacitors in both the power supply and signal path, an AHP audio-grade fuse, Mogami signal wiring, and vibration-absorbing SSC feet. The fully discrete Class A output stage delivers 400mW/60Ω and 200mW/300Ω (THD <0.001%, SNR >100dB), with four gain settings (0/10/18/20dB) via DIP switches. A phono preamplifier module option supports MM and MC cartridges, transforming the Linear SE into a two-in-one component. Dual Neutrik headphone outputs and a variable pre-output complete the specification. Dimensions: 120×296×59mm; weight: 2.2kg.

Technical background

The Linear SE upgrades the standard Linear's analogue board to Lehmann's Low-Z Copper design, reducing trace resistance and parasitic inductance for lower noise. Mundorf capacitors are used throughout the power supply and signal path — chosen after extensive listening evaluation for their combination of low measured distortion and natural musical character.

Design story

The SE designation at Lehmann Audio indicates a carefully curated set of component upgrades applied to the reference circuit — not marketing, but a documented improvement to measured and audible performance. The Copper board and Mundorf capacitors were selected over many alternatives at Lehmann's Cologne laboratory.
