Lehmann Audio Black Cube II Phono Preamplifier

Black Cube II Phono Preamplifier Delivers Precision Audio Reproduction

Black Cube II Phono Preamplifier is a low-noise, high-fidelity preamp engineered for vinyl enthusiasts who demand transparency, adaptability, and refined sonic performance. Developed by Lehmann Audio, this redefined classic integrates precision analogue circuitry with modern componentry, offering unmatched synergy with both MM and MC cartridges—even exotic low-output designs.

Black Cube II Combines Low-Noise Architecture with Ultra-Precise RIAA Equalisation

Black Cube II Phono Preamplifier is built on a sophisticated low-noise architecture, designed to maintain signal purity from cartridge to amplifier. At the heart of the unit lies an ultra-precise passive RIAA equalisation network, constructed with super-grade, closely matched polypropylene foil capacitors. This configuration, positioned between two linear gain stages, ensures excellent transient response and superb channel balance, accurately preserving the tonal integrity of the original recording.

Black Cube II Offers Flexible Cartridge Matching and Custom Impedance Control

Black Cube II Phono Preamplifier adapts effortlessly to your analogue setup thanks to its wide gain range (36 dB to 66 dB) and versatile impedance options. Each channel features a solderless custom impedance slot and a hardwire slot for immediate effect, allowing seamless integration with a broad spectrum of moving magnet and moving coil cartridges. A soft bass roll-off filter with 16 selectable frequency settings (from 7 Hz to approximately 90 Hz) provides further control over subsonic rumble and resonance management.

Lehmann Audio even supplies matching resistors free of charge upon request, enabling precision cartridge loading without guesswork.

Black Cube II Integrates Audiophile Construction with Mechanical Damping

Black Cube II Phono Preamplifier is housed in a non-magnetic aluminium chassis, topped with a mechanically dampened lid to eliminate microphony and internal resonance. These construction choices significantly reduce unwanted interference, helping to preserve clarity in delicate passages and dynamic peaks alike. The gold-plated RCA connectors and shielded power cable ensure reliable signal transmission and effective EMI suppression.

Black Cube II Delivers Punchy, Transparent Sound with Immersive Dynamics

Black Cube II Phono Preamplifier impresses with its articulate, low-distortion output. High-quality dual-sided PCBs, featuring dedicated subassemblies for hum and RF suppression, ensure smooth, consistent signal flow. Professional-grade input stages provide outstanding headroom and detail retrieval, capturing the micro-dynamics and spatial depth of every performance.

Whether you’re rediscovering classical compositions like Smetana’s Moldau, chasing the energy of jazz recordings like Eva Kruse’s New Legend, or unlocking new textures in contemporary pressings, the Black Cube II reproduces them with finesse and authority.

Black Cube II Expands Into SE Configuration with Optional PWX Power Supply

Black Cube II Phono Preamplifier can be upgraded into a Black Cube SE model simply by integrating the PWX external power supply, offering even lower noise floor and enhanced resolution. With faceplate finishes available in silver, black, or chrome, it pairs aesthetically with other high-end components such as the Lehmann Audio Linear series, becoming a centrepiece in any premium hi-fi rack.
