Lehmann Audio Black Cube SE MM/MC Phono Stage

  • Complete with PWX Power Supply
One the most revered phono stages on the market today, the Lehmann Black Cube SE! With its outboard PWX power supply, user-adjustable DIP switches for gain and loading options, improved parts and additional chassis damping, the Black Cube SE belts out the music! Experience more musical resolution and detail, better bass response and a completely silent background with the Black Cube/Power Cube PWX combination.

Great sound and versatility at a very reasonable price. In our listening tests we have found the Black Cube to be very fast and detailed with the ability to project an extremely realistic three-dimensional soundstage. Two PCB mounted DIP switches offer adjustable gain and loading options for almost all cartridges. Three gain levels, version 2 improves parts quality and adds chassis damping.

The Black Cube is a phono stage developed for the analogue music lover. The small box can be placed near by the turntable, and a wide variety of  cartridges can be connected ranging from MC to high-output MM.

The passive RIAA-network of the Black Cube is placed between two linear amplifier stages - highly buffered special amplifiers by Analog Devices. This minimizes nonlinearities caused by phase errors that would occur in active filters. The use of low tolerance WIMA capacitors results in a very stablesonic impression with a fast attack response, delicate tonal balance and realistic soundstage information.

The external regulated power supply of the Black Cube can be placed up to 2m away from the audio section. The cable between power supply and audio section is shielded to keep RFI away from the near noiseless and highly stable supply voltages. This effect is enhanced by additional supplyvoltage filtering on the double sided audio PCB.

Analogue guru Michael Fremer gave the Black Cube his highest praise in his Analog Corner column in the October '98 Stereophile: "...get your hands on the Lehmann Audio Black Cube. I don't know of anything at or near the price, or maybe even twice the price, that sounds this good." Stereophile rated Class B.
