Lehmann Black Cube SE II Phono Preamplifier
Taxes & Shipping Included
The advanced version of the multi-awarded Black Cube SE has a lot to offer: based on the SE audio circuit, the SE II has been upgraded with superior sockets, visually it excels by a housing with a faceplate. A bass filter, which can be finetuned extensively to your personal needs, takes the performance of the Black Cube series to a new level. As the proud owner of a Black Cube SE II you will get the feeling as if the music had been composed just for you. There is hardly a system that can be tailored so individually to your listening habits and acoustic preferences like this technical masterpiece. The Black Cube SE II will bring you and your favourite music together even more closely!
Virtually all common systems from high-output MM to MC may be connected to the Black Cube SE II. We have included a free slot per channel for the solder-free fitting of a custom impedance, and there is also an extra hardwired plug-in location with immediate action. Should you wish some resistors to match your personal system to the Black Cube SE II, we will enclose them with your order at no cost.
The high-precision passive RIAA filter network sits between two linear gain stages and has been realised using high-grade, surge-proof and narrow tolerated polypropylene foil capacitors. That way transients, dynamics and timbres can reach the listener in a pure manner. As with the whole Black Cube family, the Black Cube SE II also uses professional input stages of the latest generation for a precise, low-noise and powerful reproduction. The audio section contains additional modules for an efficient hum, HF and random voltage suppression. The use of a double-sided audio board allows an optimised trace layout for a particularly low-interference operation.
Due to a custom-designed toroidal mains transformer with a static shielding, the strong and seriously oversized external power supply ensures a particularly safe operation. Neutrik XLR connectors with gold-plated pins provide the safe contact between audio section and PWX power supply; the cable between audio and power section is shielded. Furthermore, the two housings are made of a non-magnetic material (aluminium) and their top lids are mechanically dampened.
By the way, with its high-class front panel (silver, black or chrome-plated) the Black Cube SE II also cuts a fine figure in your hifi rack.

About
Lehmannaudio Vertriebs GmbH was originally founded in 1988 by Norbert Lehmann, a young audio engineering student, in Cologne, Germany. Through those early days, Norbert developed a deep understanding of how the quality of certain electrical devices affected the end sound-performance of an amplifier. The cumulative result of this formative period was manifest in 1995, when Lehmannaudio released the Black Cube phono stage.
The Black Cube is now a cult object in the audiophile market. Still available today in almost the same form as the original model, the Black Cube took components more commonly found in studio mixing desks and brought them to a hi-fi product. The result was an affordable phono stage that sounded truly sublime. In 2004, the next icon was born; the Linear Headphone Amplifier (originally called Black Cube Linear) again took studio principles and brought them to the hi-fi sector, allowing hi-fi fans to experience the true engineering ability of Norbert Lehmann.
Since 2004 the phono stage and headphone amplifier sectors have been happy homes for Lehmannaudio products, and now the company can boast a range of products in each sector that are suitable for all budgets and technical requirements.
