Offered is „V 70 Class A mit KT 120 von Februar 2021“ 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 5219964412 ends on 04.11.2026 at 06:39 o'clock.
This looks like a fair ask, slightly on the sensible side of the market. At €5,800, it sits just above the €5,736 median and well inside the usual €3,621 to €7,946 used range, so it’s not a steal, but it’s priced where a clean, desirable example can make sense.
Octave gear has a strong reputation for refinement, drive, and long-haul reliability, and the KT120 version is especially attractive if you want real tube character with enough grip for demanding speakers. The 2021 date is a plus, since it suggests relatively recent provenance and less looming service risk than older tube pieces. If condition is genuinely good and the seller can document care and tube hours, this is the kind of listing an enthusiast can buy with confidence.
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.
