Lehmann Audio Black Cube SE II Phono Stage

The Lehmann Audio Black Cube SE II Phono Stage is an advanced version of the multi-awarded Black Cube SE has a lot to offer: based on the SE audio circuit, the Lehmann Audio Black Cube 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 Lehmann Audio 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 Lehmann Audio Black Cube SE II Phono Stage. 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.
