LEHMAN AUDIO BLACK CUBE SE II

MM/MC Phono Stage consisting of the Black Cube and the PWX power supply.

The advanced version of the multi-awarded Black Cube SE brings numerous improvements over its predecessor. Based on the audio circuit of the SE, the SE II has been enhanced with high-quality connectors and features an elegant design. The new model also includes a fully adjustable bass filter, allowing for performance optimization based on personal preferences, taking the Black Cube series' sound quality to a new level.

Owning a Black Cube SE II means experiencing music as if each track was composed specifically for the listener. The ability to customize the system to one's sonic preferences is a unique feature, allowing for a sound perfectly tuned to individual listening habits. The Black Cube SE II brings the listener closer to the music in a way that few other systems can.

The Black Cube SE II is compatible with virtually all turntable systems, from high-output MM cartridges to MC models. It includes a channel slot that allows the installation of a custom impedance without soldering, as well as a plug-in connector that can be quickly activated for added flexibility.

The high-precision passive RIAA filter sits between two linear gain stages and is made using polypropylene film capacitors known for their excellent quality, surge resistance, and tight tolerances. This ensures that the Black Cube SE II can reproduce transients, dynamics, and timbres in a crystal-clear and detailed manner. Like other models in the Black Cube family, the SE II uses the latest generation professional input stages, guaranteeing precise, low-noise, and powerful reproduction. The audio section also features modules dedicated to suppressing hum, high-frequency interference, and electrical noise, while the double-sided audio board layout optimizes trace routing, further reducing interference.

The external PWX power supply features a custom-designed toroidal transformer with static shielding, ensuring safe and protected operation. Neutrik XLR connectors with gold-plated pins ensure a stable, distortion-free connection between the audio section and the power supply, while the cable connecting the two sections is shielded to prevent interference. The enclosures are made of non-magnetic aluminum with mechanically dampened top covers, further enhancing stability and reducing external noise.

With its high-class front panel, the Black Cube SE II is not just a technical masterpiece, but also a design object that enriches the aesthetic of any hi-fi setup, adding elegance and style.
