Lehmannaudio Black Cube II Phono Preamplifier Black

Lehmann Audio Black Cube II – High Precision MM/MC Phono Stage

The Black Cube II represents the evolution of Lehmann Audio's legendary Black Cube series, combining the German brand's renowned sound quality with superior construction solutions. Thanks to meticulous attention to detail and the use of selected components, this phono stage is able to make the most of any MM or MC cartridge, delivering a dynamic, detailed and incredibly natural sound.

Main Features

Universal compatibility with MM and MC cartridges, thanks to infinite impedance adjustment possibilities.

Gain and load selectors with gold-plated contacts, for always optimal signal transmission.

High-precision RIAA circuit, made with low-loss MKP paper capacitors and low-noise metal film resistors.

Gold-plated RCA input and output, to ensure the highest connection quality.

16-step configurable low-pass filter, to customize the low-frequency response according to your musical tastes.

High-quality external power supply, designed to ensure a wide dynamic range and noise-free reproduction. of distortion.

Non-magnetic aluminum chassis, reinforced and damped to eliminate unwanted vibrations, derived from the higher-end Black Cube SE II model.

Build Quality and Performance

The highly accurate passive RIAA equalization network is positioned between two linear gain stages. The capacitors used are high-transient and extremely low-tolerance, to ensure a neutral and detailed sound response.

The double-layer audio interface with separate ground guarantees a clean and interference-free signal path, while the professional input stages use the latest generation components to minimize background noise.

The result is a transparent, dynamic and three-dimensional sound, capable of restoring even the most subtle nuances of the original recordings — ideal for those who want to rediscover their vinyl with surprising realism.
