Turn your computer into a High End audio source!


Lehmann Audio Black Cube Linear USB headphone amplifier offers the award winning performance of the standard Linear, with the added benefit of USB connectivity and automatic input selection. In similarity to the standard Linear, the Linear USB offers a wonderfully rich sound with most types of headphones.

It features two parallel headphone outputs allowing you to use it with two pairs of headphones and also an additional line output. Gain is switchable underneath (between 0dB/10dB/20dB) allowing you to match it accurately to the headphones in use.

In addition to its wonderful performance, the Linear USB is one of the first high end headphone amplifiers to also offer reference quality listening from a PC or laptop. The Linear USB features a built in DAC which accepts a digital input via USB cable (bypassing your sound card). It will also automatically select the input being played, allowing you to leave both your standard source and PC or laptop plugged in at the same time if you wish. Sit back, listen and enjoy.
