Offered is „CS-300X(S) 4 x EL84, 2 x 15 Watt, Highest Grade Parts“ by Leben as exhibit from the category „Tube-Fullamp“ on audio-markt.de - the online market place for high-end. The advert with the number 8309652069 ends on 01.11.2026 at 06:09 o'clock.
Good condition at €4,500 puts this above the recent used median of €3,457 and even past the €3,985 upper quartile, so it reads as ambitious rather than a bargain. For a standard used piece, that’s a lot of ask unless this one has unusually strong provenance or a notably complete package.
What keeps it interesting is the usual Leben appeal: a compact, musical integrated with real cult following, excellent tone density, and enough refinement to stay engaging without sounding clinical. If the cosmetics are excellent, it’s from a careful owner, and the box, remote, and paperwork are all present, it can still make sense for someone specifically chasing this sound; otherwise, I’d want room to negotiate.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
