Lehmann Audio Decade

Decade

At the High End show in Munich 2005, Lehmann audio announced the release of a new phono stage, named Decade, to celebrate the first decade of Black Cube phono stages and to effectively fill the huge gap between the company‘s own Black Cube SE and the Silver Cube reference phono stage. The Decade is the top model of the Black Cube series of phono stages.

Key Features:

Audio Section:

The input stages used in the Decade can also be found in top notch mixing consoles or in well known professional microphone preamps.

The passive filter network between two linear gain stages realized with precision MKP caps

Several resistive and capacitive load options as standard

Front switchable gain (36dB - 66dB) and soft bass rollof

Onboard slot for custom impedance

Zero global feedback Class A output stage technically identical with Black Cube Linear

High quality gold plated pcb mount RCA connectors for audio

High quality double sided printed circuit board for optimal signal routing

Neutrik connector with gold plated contacts for supply connection (as Silver Cube)

Faceplate anodized aluminium in either black or silver finish

PWX II Power Supply:

Power supply outlets for two audio devices

30 VA toroidal transformer of the PWX II power supply is a key component for the sonic performance achieved with the Black Cube Decade. This transformer is not only over dimensioned but sports a grounded isolation coil between the primary and secondary coil.

Neutrik connectors with gold plated contacts for supply connection (as Silver Cube)

Downward compatible with PWX. Black Cube SE audio sections can be connected.

High quality double sided printed circuit board for optimal signal routing

Faceplate anodized aluminium in either black or silver finish
