LEHMANN AUDIO BLACK CUBE

Second-hand. In excellent conditions. No visible signs of wear. Comes with original packaging, manual, and external power supply.

The Lehmann Audio Black Cube is a high-end MM/MC phono preamplifier designed for those who seek the ultimate listening experience from their vinyl collection. Created by German engineer Norbert Lehmann, this device is built to deliver studio-quality performance, stripping away unnecessary aesthetic elements to focus entirely on sonic excellence.

Inside its minimalist design lies a precision RIAA circuit, built with top-tier components such as WIMA MKS capacitors, low-noise resistors, and Analog Devices operational amplifiers. The separate power supply, equipped with advanced interference filters, ensures exceptionally stable voltage, minimizing distortion and background noise.

The Black Cube stands out for its versatility: with internal switches, it allows for impedance and capacitance adjustments, making it compatible with a wide range of cartridge types for unparalleled customization. The frequency response is remarkably extended and detailed, delivering deep, controlled bass, crystal-clear mids, and well-defined highs that remain fatigue-free. The soundstage is wide and three-dimensional, offering a truly immersive and lifelike listening experience.

Ideal even for the most demanding audiophiles, the Lehmann Audio Black Cube is the perfect choice for those who desire a refined-sounding phono preamplifier with a build quality designed to last.
