Lehmann audio Black Cube SE Phono Stage

Description

The Lehmann audio Black Cube SE Phono Stage is equipped with the extra potent PWX power supply, taking the performance of the Lehmann audio Black Cube Standard Phono Stage to another level. Just imagine you could get even more out of your favourite record: the Black Cube SE does it with far greater bass authority, very relaxed mid and enhanced top end sparkle and openness.

Owing to its 66 dB of maximum gain, virtually all common systems from high-output MM to MC may be connected to the Lehmann audio Black Cube SE Phono Stage. There is a free slot per channel for the solder-free fitting of a custom impedance and an extra hardwired plug-in location with immediate action. Should you wish some resistors to match your personal system to the Black Cube SE, we will enclose them with your order at no extra 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. The audio section contains additional modules for an efficient hum, HF and random voltage suppression. The use of a double-sided audio board also offers additional ground planes for a zero-interference operation.

The external PWX power supply is equally compact in size like the audio section, so the Lehmann audio Black Cube SE Phono Stage may be placed right next to your turntable drive, thus minimising potential losses due to cable lengths and leaving no chance for acoustic detriments. Neutrik XLR connectors with gold-plated pins provide the safe contact between audio section and PWX power supply, the connection 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.
