Lehmann Audio specifications

Category : Manufacturer

The company owner is Dipl.-Ing. Norbert Lehmann. Lehmannaudio was founded in 1988, initially with a focus on sound recordings. From 1992 onwards, phono preamplifiers, balancing stages and preamps were manufactured in small series under the ENTEC label. At the beginning of 1998, the company name was changed to Lehmannaudio. The Black Cube Phono preamplifier has been on the market since 1995. The reference phono preamp Silver Cube has been around since 2002.

In 2004, the headphone amplifier Black Cube Linear appeared, which is now sold only under the name Linear.

In July 2007 the relocation from Köln Porz to Bergisch Gladbach took place. Since August 2010 the company Lehmannaudio Vertriebs GmbH has been merged into the company Lehmannaudio. Lehmannaudio products are available in about thirty countries worldwide.

Since March 2018, the company's headquarters have been back in Cologne

Headphone amplifier

Hifi Headphone Amplifier

Rhinelander headphone amplifier with Class-A output stage without over-all feedback. Power supply: Wide-range switching power supply (since about January 2011) - Production discontinued

Linear headphone amplifier with Class-A output stage without over-all negative feedback. Power supply: Linear power supply with specially manufactured toroidal transformer with grounded shield winding (static shield)

Linear II headphone amplifier with Class-A output stage without over-all negative feedback. Power supply: Linear power supply with specially made toroidal transformer with grounded shield winding (static shield) The Linear II mainboard is equipped with LOWZ copper, Mundorf capacitors in the power supply and signal path and mica capacitors. The device has the 3S device feet as standard.

Linear D headphone amplifier with Class-A output stage without over-all feedback. Power supply: Linear power supply with specially made toroidal transformer with grounded shield winding (static shield). Additionally built-in DAC with optical (Prio 1) and coaxial (Prio 2) input. The digital inputs are prioritized among themselves. If no digital signal is detected, an automatic fallback to the analog input takes place. This makes it possible to use it as a preamplifier for two digital and one analog source. The Linear II mainboard is equipped with Lowz copper, Mundorf capacitors in power supply and signal path and mica capacitors. The device has the 3S device feet as standard.

Linear USB headphone amplifier with Class-A output stage without over-all feedback. Additionally built-in USB D/A converter. The source selection is automatic: The USB converter is switched on as soon as the Linear USB detects a valid audio data stream.
