The Black Cube is the classic among phono preamplifiers: since its market launch in 1995, it has enjoyed cult status among countless record lovers and has caused a sensation in the trade press with its compact dimensions and magnificent sound. Since 2006, the audio board has been available on the market in a new, significantly improved version.

Do you remember the first time you put on your favorite LP? Which detail captivated you then and continues to thrill you today? The Black Cube makes a reunion with beloved music classics possible: thanks to outstanding components and sophisticated circuit design, the sound is reproduced true to the original and full of depth, despite its tiny dimensions.

“For anyone looking for what might be the world’s best phono stage for under $2,000, I can proudly recommend the Lehmannaudio Black Cube.”

Characteristic of the Black Cube are its wide spectrum of tonal colors and its almost explosive dynamics. The reason for this is the high-precision, passive RIAA equalization network located between two linear amplifier stages. This is realized using low-loss, precision MKP film capacitors. The high-quality input stages of the latest generation ensure low-noise reproduction; it is not for nothing that they are also used in high-end mixing consoles and microphone preamplifiers. The specially developed power supply guarantees high overload resistance.

Quality meets flexibility

The maximum gain of the Black Cube allows you to connect practically all systems common on the market, from high-output MM to MC. The configuration options ensure almost limitless freedom of choice: a free slot for a custom impedance also offers a suitable termination for demanding MC systems. All resistors are low-noise metal film types. For switching gain and impedance, we naturally only use switches with gold-plated contacts. In addition, there is an extra hardwire slot per channel, which acts directly without a switch.

The flexibility of the Black Cube is also evident in the positioning of the device: you can easily place it right next to the tonearm of your turntable. This is made possible by the cable between the power supply and the audio section, as well as the compact dimensions of this phono stage, which are typical for the entire Black Cube series. The shielded cable is equipped with an original Neutrik XLR connector on the power supply side. Furthermore, the housing of the audio section is made of non-magnetic material (aluminum) and is mechanically damped in the lid. Inside the audio section, there are additional modules for effective hum, HF, and noise voltage suppression. The use of a double-sided audio board also allows for additional ground planes for interference-free operation.
