Lehmann Black Cube Original Phono Preamp
Black Cube: Cult object since 1995 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. The low noise regulated external power supply is connected with Neutrik XLR connectors to the dedicated DC 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. "This $695 MM/MC need not apologize for itself in any way at any price - that's how good it is." Stereophile Review of the Black Cube "... get your hands on the Lehmann audio Black Cube. I don't know of anything at or near the price, that sounds this good. The Audiophile Voice Reviews the Black Cube "Without the slightest hesitation or reservation, I can wholeheartedly recommend the Lehmann Audio Black Cube phono stage for inclusion in any high-end analog playback system. It offered performance comparable to my reference phono preamp for a small fraction of its price and I'd call that a bargain -The Best I Ever Had!"

Ratings & Reviews
Very good choice for wide frequency range mid cost MC cartridges, but it can really astonish us running with the best MM cartridges
