Lehmann Audio Linear Headphone Amplifier

Black Cube Linear With the launch of the Black Cube Linear there is now an upscale headphone amplifier designed for the highest demands. It features a selectable gain (0dB, 10dB, 20dB) that effectively optimizes the output level of the zero global feedback Class A output stage.

For stereo setups with just one source, like a CD player or a turntable with a phono stage, the Black Cube 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 contacts. No external Y-adapter needed.
