Lehmann Silver Cube Phono Preamplifier
Taxes & Shipping Included
The Silver Cube plays in the league of the world’s consummate phono stages. Dressed in a noble guise and with finest components, it delivers an excellent sound and thus clearly belongs to the best things that can happen to your records. Look forward to a priceless musical experience, let yourself get carried away by the masterful acoustic performance of our attractive top model. The listening delight provided by your records is a very unique experience for you which can only be compared to the magic of a live concert? Besides concentrated energy you also expect matchless transparency, a captivating wealth of detail and a spectacular three-dimensional reproduction of space when enjoying your favourite LPs? Then the Silver Cube offers you everything you ever dared to dream of.
To make the Silver Cube perfect, we have put our decades of experience and all our audiophile passion in the balance. Like always we use the best components from first-class makers. With love for detail we have optimised circuits and raised the mechanical system to a downright masterful level.
The Silver Cube can display its excellence in combination with almost any MM and MC systems available on the market. For this purpose the adjustable gain between 36 dB and 66 dB gives you the necessary flexibility. Finest ingredients such as high-grade Mundorf tin foil capacitors in the filtering network, mica capacitors in the input section, WBT Nextgen sockets for the signal connection and our vibration-damping 3S Device Feet: these are important, yet nowhere near all reasons for the top performance one can experience with the Silver Cube. In any case, one thing soon becomes clear: the Silver Cube is not suitable for fault compensating chains.
The adaptations described provide breathtaking dynamics, excellent specifications as well as an impressively holographic imaging. The sheer elegance of this phono stage once again shows in its high-class aluminium design. It does not only serve as a heatsink for the discrete class-A output stage with no overall negative feedback, but also makes the Silver Cube the visual the star of your high-end system.

About
Lehmannaudio Vertriebs GmbH was originally founded in 1988 by Norbert Lehmann, a young audio engineering student, in Cologne, Germany. Through those early days, Norbert developed a deep understanding of how the quality of certain electrical devices affected the end sound-performance of an amplifier. The cumulative result of this formative period was manifest in 1995, when Lehmannaudio released the Black Cube phono stage.
The Black Cube is now a cult object in the audiophile market. Still available today in almost the same form as the original model, the Black Cube took components more commonly found in studio mixing desks and brought them to a hi-fi product. The result was an affordable phono stage that sounded truly sublime. In 2004, the next icon was born; the Linear Headphone Amplifier (originally called Black Cube Linear) again took studio principles and brought them to the hi-fi sector, allowing hi-fi fans to experience the true engineering ability of Norbert Lehmann.
Since 2004 the phono stage and headphone amplifier sectors have been happy homes for Lehmannaudio products, and now the company can boast a range of products in each sector that are suitable for all budgets and technical requirements.
