Offered is „V 80 SE“ 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 2255678702 ends on 26.12.2026 at 12:14 o'clock.
New pricing was around €10,120, making €5,500 a strong used-market buy rather than merely fair. It sits below the €5,833 median and well above the €2,877 25th percentile from 27 comparable listings, so the asking price looks attractive for a clean example.
The V 80 SE is a particularly capable valve integrated: four KT150s deliver serious power and grip, with the transparency, bass authority and spaciousness that make Octave gear compelling. It also offers balanced input, flexible pre/power separation, optional phono, headphone output and home-cinema bypass. At this price, check tube age, biasing, remote, and whether the phono module is fitted, but none is a reason to hesitate if the amplifier is healthy and complete.
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.
