Offered is „V 50 MK2 LINE mit Super Black Box“ by Octave as second-hand device from the category „Tube-Fullamp“ on audio-markt.de - the online market place for high-end. The advert with the number 7924879102 ends on 13.11.2026 at 22:26 o'clock.
Think of this less like paying for a generic 50-watt tube integrated and more like getting into Octave at a sharp entry price: at €2,400, it lands well below the €3,159 25th percentile and miles under the €5,789 median, so this is a strong deal rather than just fair value. Against the €7,780 upper quartile, it’s very clearly priced to move.
That makes it especially appealing because Octave’s V-series has a solid reputation for refinement, drive, and real-world speaker compatibility, and the Super Black Box adds meaningful power-supply muscle. In good condition, this looks like the kind of purchase that lets you buy the sound first and worry less about paying full market. The main buyer check is simple: confirm the Black Box is included, properly connected, and fully functioning, since that accessory is a big part of the value here.
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.
