Lehmann Black Cube Improved Phono Stage / Preamp

Lehmann Black Cube Improved Phono Preamplifier / Preamp - A Classic!
A phono stage with a high precision passive RIAA network. Switch between MM and MC cartridges. Various settings possible.

Since the market introduction in 1995 the Black Cube phono stages by Lehmannaudio have become cult objects for analog oriented music lovers. Countless positive reviews and awards, and an unrivalled customer satisfaction worldwide document this truly exceptional success. The Black Cube is produced in small numbers and sonically superior to mass industry products.
The Lehmannaudio Black Cube phono stage is compatible with practically all available cartridges on the market from High Output MM to the lowest output MC cartridges. Apart from the standard switch settings there is one onboard slot that can be fitted with a custom impedance to supply perfect termination even for the most exotic cartridges. Since 2006 there is a separate hard wire custom impedance slot that needs no DIP-switch to be activated. Customisation possibilities are infinite. No more need for expensive impedance plugs!

Newly developed input stages
The newly developed input stages used in the Black Cube can also be found in top notch mixing consoles or in well known professional microphone preamps. The entirely passive RIAA equalization network is realized with high precision MKP capacitors. All resistors are of the low noise metal film variety. The switches for gain and load settings have gold plated connectors.

Because of the small outer dimensions the Black Cube can be placed next to the turntable. This minimizes loss due to cable lengths. Low noise regulated external power supply.

Lehmannaudio always pays special attention to details: the cable between power supply and audio section is shielded. The cases of both the power supply and the audio section are made of nonmagnetic materials and the case of the audio section is even equipped with a top cover coated with a special anti-resonance treatment.
