Angeboten wird „Jubilee 300b“ von Octave als Gebrauchtgerät aus der Kategorie „Röhren-Endverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 377036958 endet am 27.07.2026 um 19:10 Uhr.
Set against the current used market, €34,500 is well above the typical level for comparable listings: it sits far beyond the €9,948 75th percentile and is roughly 6× the €5,825 median. That makes this an ambitious ask, not a fair-market buy, unless there’s something genuinely exceptional behind it.
What keeps it interesting is the model itself: Octave’s 300B-based flagships are valued for big, fluid triode sound, excellent scale, and the kind of low-level texture and image density that makes serious tube listening addictive. If this one is cosmetically clean and fully sorted, the upside is in the performance, but at this price I’d want proof of a recent service, strong tube health, and complete accessories/documentation before considering it.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Octave Audio traces its roots to 1968, when Karl Heinz Hofmann established a transformer winding factory in Karlsbad, Germany. His son, Andreas Hofmann, joined in 1975, developing early semiconductor and tube amplifiers. In 2000, Andreas took the helm, rebranding it as Octave Audio to channel his decades-long passion for tube-based electronics into high-end hi-fi components.
The brand specializes in meticulously hand-built tube amplifiers, including preamplifiers, power amps, and integrated models like the V 16 Single-Ended and Jubilee series. Octave emphasizes premium features such as external power supplies, balanced connectivity, adjustable gain, and modular upgrades for phono stages and power conditioning. Their in-house transformer expertise ensures low-noise performance across full-range designs, from 8-watt single-ended units to 30-watt powerhouses.
Positioned firmly in the high-end market, Octave commands respect among audiophiles for its German craftsmanship, sonic purity, and innovative tube technology. Hand-assembled with top-tier components at their Karlsbad headquarters, these amplifiers deliver uncompromising musicality, appealing to discerning buyers seeking perfection over mass production.
