Product Description

Lehmann Audio Black Cube Linear is a high quality headphone amplifier is as important for listening to music with a pair of headphones as are stable power amplifiers for the loud-speakers of your stereo setup.

Headphone Amplifier

For the same sound pressure level the power needed with non-dynamic headphone models can vary up to a factor of about 500! Impedances can be different to a factor of more than 20! Diverse models have specific requirements to the headphone amplifier driving them in terms of voltage and current. Linear provides a high end headphone amplifier solution to realize even the highest demands to reference quality headphone audio reproduction.

Selectable Gain

The selectable gain 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 notch listening pleasure. Now hear that ultra transparent sound and the explosive dynamics formerly known only from electrostatic headphones.

Power Supply

An over dimensioned power supply with a huge magnetically and statically shielded toroidal transformer is included internally allowing a power cable of your choice to be directly connected to the unit. The faceplate and huge milled aluminium knob for smooth running 27mm ALPS volume control come in anodized black or silver. 

Source Choice

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 contacts. No external Y-adapter is needed. 

Use the Linear to get more from your Audio Technica, Beyerdynamic, Goldring, Grado, Sennheiser, Ultrasone or other model headphones.
