Built with typical Japanese attention to detail, it is a true collector’s piece and a joy to listen to.Includes: • Original packaging • All factory accessories • Original tubes in excellent conditionThis is a rare opportunity to own a nearly-new CS-300F without the wait or full retail price (currently, way north of 4000 euros).
Generating expert take…
Leben Hi-Fi Stereo Company emerged from the vision of Taku Hyodo, a renowned Japanese tube audio engineer formerly with Luxman. After founding Kouri Denki Co. in 1979 to produce electronic components, Hyodo released his first commercial amplifier, the Triode 33 under the KFH brand, in 1991. He established Leben in 1992—drawing its name from the German word for "life," reflecting his philosophy that music is life—with the debut RS-35a power amplifier in 1995, followed by the RS-28c preamplifier in 1998.
The brand specializes exclusively in hand-built vacuum tube amplifiers, including integrated models like the celebrated CS-300 series, power amps, and preamplifiers. Crafted with point-to-point wiring, premium components, and often rare NOS tubes, Leben eschews mass production for meticulous, small-batch assembly by a skilled team. Features such as headphone outputs, bass boosters, and speaker selectors enhance versatility, while remote controls are notably absent in favor of pure analog focus.
Leben occupies a niche boutique position in the high-end hi-fi market, prized by tube enthusiasts for its musicality, reliability, and lifelike sound. Once Japan-exclusive, its global cult following has grown through limited exports, earning acclaim in audiophile circles as passion-driven masterpieces that deliver rewarding performance without compromise.
