Angeboten wird „V 70 Class A Röhrenvollverstärker mit SUPER BLACK BOX“ von Octave als Gebrauchtgerät aus der Kategorie „Röhren-Vollverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 778178129 endet am 28.07.2026 um 08:51 Uhr.
This one matters a bit because it’s a higher-powered, later-generation Octave integrated with the external supply, so condition and service history matter more than pure age. At €7,750, it sits above the €5,799 median and just under the €8,124 75th percentile for recent used EUR listings, so this reads as a fair-to-strong asking price rather than a bargain.
What makes it attractive is the Octave house sound: refined, quiet, dynamic, and unusually controlled for a tube amp, with the SUPER BLACK BOX typically bringing better grip, scale, and bass authority than the amp alone. If the unit is clean, properly serviced, and includes the box and cable, this is the kind of package that can justify paying near the upper end because you’re buying performance and flexibility, not just wattage.
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.
