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.
Like every Lehmann Audio 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
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.
