Evolution of a classic

The Black Cube II combines the tonal foundation of the well-known Black Cube with the higher-quality connectors and elegant housing design of the Black Cube SE II. Like its predecessors, it extracts the full tonal spectrum from almost all MM and MC cartridges – precise, dynamic, and musical.

High-precision RIAA equalization

The heart of the Black Cube II is the passive, extremely accurate RIAA filter network, which sits between two linear amplifier stages. Polypropylene film capacitors with tight tolerances ensure an unadulterated sound image and enable a level rarely found in this price range.

Elaborate power supply & low-noise circuitry

The newly developed power supply offers high overload stability and operates with particularly low interference. The non-magnetic aluminum housing is additionally damped, while the professional input stages ensure particularly low noise and powerful, clean dynamics. Hum and HF interference are effectively suppressed by additional components.

Flexible adaptation to any system

For perfect matching, there is a slot for optional impedances per channel as well as a direct hard-wire slot. Upon request, Lehmann Audio supplies suitable resistors free of charge. This allows the Black Cube II to be individually tuned to cartridges and sound preferences. harmonized.

Finely adjustable bass filter

With its bass filter, which can be adjusted in 16 different steps between 7 and approx. 90 Hz, the low-frequency range can be specifically adapted – ideal for optimizing room acoustics or cartridge systems.

Elegant design in the hi-fi rack

Visually, the Black Cube II impresses with high-quality front panel variants in silver, black, or chrome. In combination with Linear & Co., an harmonious, modern overall appearance in the rack is achieved.
