Lehmann Audio Decade

2 Box phono stage. Lehmannaudio is has built a reputation and unrivalled customer satisfaction on the sound and build quality of phono stages. The ambitious Decade effectively fills the gap between the Black Cube SE II and the Lehmannaudio reference phono stage, the Silver Cube. In the Decade, like in all Lehmannaudio devices, top notch technology is used that normally can be found only in price ranges far above.

The input stages of the Decade can also be found in top notch mixing consoles and high class microphone preamps of professional studio electronics. The highly accurate, passive RIAA equalisation network is placed between two linear gain stages and uses precision MKP capacitors. This results in a very stable soundstage reproduction and pin point localisation of instruments.

The maximum gain of 66 dB is well enough for even very exotic low output MC cartridges. Impedance load adaption is practically infinite as with all Lehmannaudio phono stages: there is a free slot for a custom impedance so that every existing MC cartridge on the market can be loaded properly. Input capacitances are adjustable as well.

The Decade is the first phono stage by Lehmannaudio that offers a “Soft-Bass- Rolloff-Filter” and gain selections accessible via toggle switches at the face plate. Both, gain and filter functions, are executed by studio grade relais inside the unit.

The Decade is powered by the PWX II, a power supply especially developed for the unit which is downward compatible with the PWX. This means that Black Cube audio sections can also be connected. The second power outlet at the PWX II is made especially for that purpose. The PWX II power supply with chokes at critical places powers the Decade with very clean DC power and – like the Silver Cube – is connected to the audio section via a shielded cable with Neutrik XLR plugs.

Brand

Lehmann Audio

Lehmann Audio Vertriebs GmbH was founded in 1988 by the young student of audio engineering, Norbert Lehmann, in Cologne, Germany. After 11 years in pleasant Bergisch Gladbach the company returned to the Rhineland metropolis in spring of 2018. Here with passion for detail is being created what has come into favour in the whole world because of it's quality: the Lehmannaudio product line. Made in Germany.

Striving for perfection

During his audio engineering studies, he was listening to two amplifiers with identical technical specifications in a direct A/B comparison. Really amazing how much they differed in sound quality: one delivered sound, the other one music. There I realised for the first time that good sound depends on much more than technical data such as power, distortion factor and signal-to-noise ratio. That listening session sparked a passion in me which has never ceased: how could he build audio technology so, that it communicates the musician's intention as musically and faithfully as possible? For him, this aspect is key in developing high end. Furthermore,  in pursuit of perfection while staying grounded. And when he finally learnt that his customers feel happy while listening
