About
Lehmannaudio Vertriebs GmbH was originally founded in 1988 by Norbert Lehmann, a young audio engineering student, in Cologne, Germany. Through those early days, Norbert developed a deep understanding of how the quality of certain electrical devices affected the end sound-performance of an amplifier. The cumulative result of this formative period was manifest in 1995, when Lehmannaudio released the Black Cube phono stage.
The Black Cube is now a cult object in the audiophile market. Still available today in almost the same form as the original model, the Black Cube took components more commonly found in studio mixing desks and brought them to a hi-fi product. The result was an affordable phono stage that sounded truly sublime. In 2004, the next icon was born; the Linear Headphone Amplifier (originally called Black Cube Linear) again took studio principles and brought them to the hi-fi sector, allowing hi-fi fans to experience the true engineering ability of Norbert Lehmann.
Since 2004 the phono stage and headphone amplifier sectors have been happy homes for Lehmannaudio products, and now the company can boast a range of products in each sector that are suitable for all budgets and technical requirements.
