Lehmann Audio BLACK CUBE II Phono Preamplifier

The Black Cube II combines the proven quality of Lehmannaudio's iconic Black Cube phono stage with the upgraded connectors and enclosure of the superior Black Cube SE II.

In typical Lehmannaudio style, the Black Cube II allows virtually any moving magnet (MM) or moving coil (MC) cartridge to shine and achieve its fullest potential, eliciting from your favourite music the complete sound spectrum of the original recording. Owing to the configurable bass filter with 16 different setting options, the Black Cube II can be perfectly tailored to your tonal preference. Its peerless dynamics let you rediscover old and new recordings – as if it were your first time!

The ultra-precise, passive RIAA filter network of the Black Cube II sits between two linear gain stages and is created using super-grade, high-transient, close-tolerance polypropylene foil capacitors. Hence this phono preamp offers the impressive, pure sound image of the premium device league at an attractive entry-level price tag. The Black Cube II is a new classic, boasting a custom-designed power supply for a wide, distortion-free dynamic range.

The enclosure of the Black Cube II is made from aluminium for its non-magnetic properties and is dampened under the lid to resist unwanted vibrations. The professional input stages used ensure an outstandingly accurate, punchy, low-noise reproduction. The audio section is equipped with additional sub-assemblies for efficient hum, HF and noise suppression. Its dual-sided audio board allows an optimised trace layout for an exceptionally smooth operation.

The Black Cube II can also be flexibly adapted to almost any system: each channel offers a slot to adjust for a custom impedance value. It's also finished with a captive, high-quality power supply cable for optimal signal transfer from the included external power supply.

Like every Lehmannaudio product, the Black Cube II is a joy to own. It delivers a truthful rendering of any quality recording from a compact chassis that looks great in any hi-fi rack. Supplied with an external power supply, it is a great addition to any aspiring audiophile-grade system.
