Lehmannaudio Black Cube II - MM/MC phono stage

Black Cube Phono Preamp
MM/MC phono stage. Infinite head impedance matching possibilities. Gain and load selectors with gold-plated contacts. RIAA stage gain made with very high precision and low loss MKP paper capacitors. Low noise metal film resistors. Input and output with gold-plated RCA. High quality external power supply. Aluminum chassis like Black Cube SE II.

The Black Cube II combines the best strengths of the renowned Black Cube family: the proven quality of the Black Cube, enhanced by quality connectors and a chassis inherited from its bigger brother, the Black Cube SE II.

The Black Cube II confirms the high quality of Lehmann phono stages, literally making any cartridge, both MM and MC, fly, capable of extracting the entire sound spectrum of the original recording from your favorite music. Also thanks to a dedicated filter for low frequencies configurable on sixteen different settings, to better adapt the reproduction to your musical preferences. The result is a dynamic sound, a wide soundstage, which will allow you to listen to old recordings again - as if it were the first time!

The ultra-precise passive RIAA filter network is sandwiched between two linear gain stages and is constructed with super-fast, high-transient capacitors wound in tight-tolerance polypropylene. This phono stage offers all the features of high-end equipment at a truly competitive price.
The power supply, very important for performance, has been designed for a wide dynamic range without distortion. The chassis of the Black Cube II is made of aluminum (non-magnetic material) reinforced and damped to avoid vibrations. The professional-grade input stages use the latest generation components and ensure an extraordinarily accurate and low-noise reproduction. The audio section is equipped with dedicated components, capable of suppressing noise and hum. The sound card is double-layer, with an optimized ground path and completely separated from the audio signal.

The Black Cube II adapts seamlessly to any cartridge: each channel has a dedicated slot for impedance matching. There is also an additional slot for testing the fit with immediate effect.
