The Lehmanaudio Linear high end headphone amplifier


  • The selectable gain (0 dB, 10 dB, 20 dB) of the Linear effectively optimises the output level of the zero global feedback Class A output stage. Practically all high quality dynamic headphones available will show their best possible performance, no matter if you have an easy to drive low impedance pair of headphones or an ineffective pair of 600 ohms studio cans.

  • Carefully selected top notch components and a highly sophisticated circuit design guarantee top performance listening pleasure. For stereo setups with just one source like a CD player or a turntable with a phono stage the Linear is the simplest and most effective active preamp one can think of. All audio connectors including the two Neutrik phone jacks come with gold plated connectors.

    The faceplate and the massive milled aluminium knob for the smooth running 27 mm ALPS high grade volume control are available in anodised black, silver, or chrome.
