About Leben Hi-Fi Stereo Company

Leben Hi-Fi Stereo Company is a Japanese firm known for producing high-quality tube amplifiers. Established by Taku Hyodo, a seasoned engineer with experience at Luxman, Leben (a German word meaning "life") reflects Hyodo's dedication to music and audio engineering. Leben amplifiers are assembled by hand, utilizing point-to-point wiring and carefully selected components. This approach emphasizes craftsmanship and results in amplifiers that combine strong sonic performance with a classic, understated design. The company's product range, while limited, addresses various audio needs and preferences. Among its most notable offerings is the CS-300 series of integrated amplifiers. Introduced in the early 2000s, the CS-300 series has undergone several updates, including the CS-300X (2006), the CS-300XS (2010) with improved transformers, and the CS-300F (2014) featuring a refined circuit design. These amplifiers, based on EL84 tubes, are recognized for their detailed sound and adaptability. For users requiring higher power output, the CS-600X (2013) is a push-pull integrated amplifier using KT-88 tubes. It provides a dynamic sound suitable for a broader range of speakers. Leben also offers the RS-28CX (2010) preamplifier, valued for its transparent sound and precise imaging, and the RS-30EQ (2008) phono stage, which delivers a warm and detailed analog playback experience. Although not widely known, Leben amplifiers have developed a loyal following among audiophiles. Their appeal lies in their robust construction, musical sound quality, and lasting value. Hyodo’s focus on quality ensures that each Leben amplifier is built to provide a reliable and engaging listening experience.
