Description

The Lehmannaudio Decade Jubilee is the MM/MC phono preamplifier that brings the Decade very close to the flagship Silver Cube model: it inherits its entire passive RIAA equalization network . The result is a clear vinyl reproduction down to the smallest details, with a wide soundstage and a naturalness that make it suitable for even the most demanding systems.

The output stage is a discrete, high-power class A , which maintains sonic quality even with long connection cables. Internally, the signal travels in dual mono , with one relay per channel: crosstalk is reduced and paths remain short. The matching options, with slots for a custom load and adjustable input capacitance between 47 and 1.370 pF, allow you to find the right setting for even the most unusual MC cartridges.

Day-to-day use is simple: gain and the "soft bass" filter are controlled with levers on the front of the audio section. The separate PWX II LC power supply has been revised with significantly more copper and higher-quality capacitors, for even faster transient response. The audio section and power supply sit on 3S anti-resonance feet developed by Lehmannaudio, and the non-magnetic aluminum enclosures have mechanically dampened lids to prevent microphonics and resonance.

What's the difference between the Decade and the Decade Jubilee? The Jubilee features the Silver Cube's RIAA network, the upgraded PWX II LC power supply, and 3S feet as standard: it's the next step for those who want to get closer to the Cologne-based company's reference amplifier without reaching its price.

About the brand

Lehmann Audio is a prestigious German hi-fi brand founded in 1988 by sound engineer Norbert Lehmann in Cologne, Germany. For over three decades, the company has been positioned in the reference high-fidelity segment, specializing in the design and production of audiophile-quality headphone amplifiers, phono stages, and power amplifiers. The company's Made in Germany philosophy guarantees high quality standards recognized internationally by the most discerning audiophiles.
The history of Lehmann Audio is rooted in a formative experience the founder had while studying audio engineering. Norbert Lehmann recounts how a direct comparison between two amplifiers with identical specifications but completely different sound quality ignited his passion for reference-level music reproduction. This epiphany led him to understand that sound quality depends on much more than simple technical data like power, distortion factor, and signal-to-noise ratio. Since 1988, the company has developed a design philosophy that prioritizes musical fidelity through meticulously selected components and circuitry, focusing investment on technical substance rather than flashy packaging. After eleven years in Bergisch Gladbach, Lehmann Audio returned to the Rhineland metropolis of Cologne in 2018, where it continues to handcraft its reference-level audio devices.
Lehmann Audio's distinctive technologies are based on proprietary innovations that have revolutionized the headphone amplifier and phono stage industry. One of the most significant innovations is low-Z copper technology: this low-impedance construction uses special printed circuit boards that cost ten times more than standard PCBs, ensuring superior dynamics and exceptional sonic performance in terms of transient response and spatial imaging. The input stages used are derived from professional mixing consoles and the highest-quality microphone preamplifiers, ensuring extremely quiet reproduction. The ultra-precise passive RIAA equalization network, built with low-loss precision MKP capacitors, is strategically positioned between two linear gain stages to preserve the naturalness of transients, dynamics, and musical timbre.
Lehmann Audio's core product range encompasses three fundamental high-fidelity categories: headphone amplifiers, phono stages, and power amplifiers. Headphone amplifiers represent the company's core business, with models designed for both home and professional use in recording and mastering studios. Phono stages cover the entire spectrum, from entry-level solutions to absolute reference models for top-tier analog systems. Power amplifiers complete the offering for high-end hi-fi stereo systems. Each category includes options for different needs and budgets, always maintaining the brand's trademark German quality standards.
The product series are divided into specific lines with distinctive technical features. The Black Cube series, launched in 1995 with the first prototype, has become a cult object among vinyl enthusiasts internationally, offering phono stages from the classic Black Cube to the Black Cube Statement. The Linear line represents the brand's best headphone amplifiers and integrated transistor amplifiers, with models such as the Linear, Linear SE, Linear Pro, and Linear D integrating award-winning analog sections with state-of-the-art digital converters. The Decade series bridges the gap between the Black Cube series and the top-of-the-line Silver Cube, offering cutting-edge technologies for the most discerning audiophile. The range also includes portable amplifiers such as the Traveller and Rhinelander, as well as legendary reference turntables supported by Lehmann Audio phono stages.
The accolades and awards received by Lehmann Audio are testament to the technical excellence recognized by the international specialist press. Respected magazines such as What Hi-Fi have awarded the Rhinelander the prestigious "Best Headphone Amplifier £300-£500" award, while StereoNET has bestowed the Applause Award on several products in the range. The Absolute Sound called the Decade "unreservedly an excellent component," highlighting its reference-level performance. SoundStage praised the crystal-clear quality of the Silver Cube, which has been named a reference product by several international hi-fi publications. Professional reviews consistently highlight the distinctive characteristics of Lehmann Audio sound: neutral balance, exceptional detail, transparency, and the ability to communicate the original musical intent.
Lehmann Audio's audiophile target audience spans both home audio enthusiasts and audio professionals. Recording engineers and mastering technicians regularly use Linear Pro amplifiers in recording studios for critical headphone monitoring. Sennheiser selected a wide range of Linear amplifiers for the presentation of its high-end dynamic models at IFA 2005. Maarten de Boer, mastering engineer and owner of "The Masters" in the Netherlands, relies on the Linear's tonal quality as a stereo preamplifier for professional monitoring. The price range extends from entry-level models around €600 to absolute reference products costing over €5000, always guaranteeing the price-performance ratio typical of German high-fidelity engineering.
Lehmann Audio's Italian distribution is managed through a select network of specialized floorstanding speaker dealers who guarantee qualified technical advice and after-sales support. Technical support is provided directly by the German parent company, with the option of upgrades and modifications even for older models. Lehmann Audio customer service offers upgrade programs for owners of older models, such as low-Z copper analog circuitry upgrades for older Linear models. Audiocostruzioni represents a point of reference for Italian audiophiles interested in Lehmann Audio products, offering specific technical expertise for power amplifiers and personalized consultancy for the configuration of reference hi-fi systems with top-quality source components.
