Lehmann Audio Black Cube S/E Phono Stage
The Lehmann Audio Black Cube SE phono stage is compatible with practically all available cartridges on the market from High Output MM to MC. Apart from the standard switch settings there is one onboard slot that can be fitted with a custom impedance to supply perfect termination even for the most exotic cartridges.
Amplification and RIAA equalisation for MM and MC cartridges
Premium components
High end Burr Brown gain stage
Small size allows installation close to record player
Metal case shields the electronics from vibrational and electromagnetic interference
2x RCA input / 2x RCA output
Separate dedicated PWX power supply
A special 30 VA toroidal transformer of the PWX power supply is the main reason for the sonic performance achieved with the Black Cube SE. This transformer is not only over dimensioned but even sports a grounded isolation coil between the primary and secondary coil. The results: much more bass authority, a more liquid midrange as well as more openness. These sonic benefits are without any doubt the reasons that more and more music lovers choose the Black Cube SE right from the start.
Lehmannaudio always pays special attention to details: the cable between power supply and audio section is shielded and uses a Neutrik connector with gold plated contacts at the power supply side. The cases of both the power supply and the audio section are made of nonmagnetic material (aluminium) and are equipped with a top cover coated with a special anti-resonance treatment.
The input stages used in the Black Cube SE can also be found in top notch mixing consoles or in well known professional microphone preamps. The entirely passive RIAA equalization network is realized with high precision foil capacitors. All resistors are of the low noise metal film variety. The switches for gain and load settings have gold plated contacts.
