Lehmann Audio - Lehmann Audio - Black Cube II - Phono Preamplifier
The Black Cube II combines the best assets of the popular Black Cube family: the proven quality of the evergreen Black Cube, upgraded by the high-class connectors and the representative enclosure of the Black Cube SE II.
Like its predecessors, the Black Cube II makes shine virtually all MM and MC pickup systems available on the market, eliciting from your favorite music the complete sound spectrum of the original recording. Owing to the lavishly configurable bass filter with sixteen different settings, the Black Cube II can be perfectly tailored to your tonal preferences. Its peerless dynamics let you rediscover old and new recordings – as if it was your first time!
The ultra-precise, passive RIAA filter network of the Black Cube II sits between two linear gain stages and is realized using super-grade, high-transient, closely toleranced polypropylene foil caps. Hence this phono preamp offers the impressive, pure sound image of the premium device league at an attractive entry-level price tag.
Our new classic boasts a custom-designed power supply for a wide, distortion-free dynamic range. The enclosure of the Black Cube II consists of a non-magnetic material (aluminum) and is dampened under the lid. The professional input stages of the latest generation ensure an outstandingly accurate, punchy, low-noise reproduction. The audio section is equipped with additional subassemblies for efficient hum, HF, and noise suppression. Its dual-sided audio board allows an optimized trace layout for an exceptionally smooth operation.
The Black Cube II can be flexibly adapted to almost any system: each channel offers a slot for the solderless fitting of a custom impedance, plus there is an extra hard-wire slot with immediate effect. If you would like to get some resistors for matching your personal chain to the Black Cube II, they will be included free of charge with your order.
