Lehmannaudio Black Cube SE II – Schwarz phono preamp

Lehmann Audio - Black Cube SE II at a glance:

The enhanced version of the multiple award-winning Black Cube SE is a real powerhouse! Based on the audio circuitry of the Black Cube SE, the SE II was supplemented with higher quality jacks and scores with a housing with a front panel. The extensively customizable bass filter definitely raises the performance of the Black Cube series to a completely new level. Owners of a Black Cube SE II will feel as if the music they are listening to was written for them because very few phono preamplifiers can be so individually tailored to listening habits and sonic preferences as this truly excellent device.

No matter what exotic cartridge system is used from high Output MM (moving magnet) to MC (moving coil), the Black Cube SE II can be adapted to it! For each channel there is a slot for the solderless assembly of the selector impedance, for which there is an immediately effective hardwire slot. The precise and passive RIAA filter network is located between two low-noise amplifier stages and is implemented with the help of high-quality and impulse-resistant MKP capacitors with a narrow tolerance. The result is optimum channel uniformity and localization with optimal impulse response. The powerful external PWX power supply with a custom toroidal transformer with a static shield ensures particularly reliable and safe operation.
