Angeboten wird „HP 300“ von Octave als Gebrauchtgerät aus der Kategorie „Röhren-Vorverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 4888154391 endet am 26.07.2026 um 14:00 Uhr.
Octave’s HP 300 is a respected tube preamp with a real following, and €750 is a strong bargain versus your recent comparable market: it sits far below the €4,342 25th percentile and well under the €6,240 median. For a well-kept example, that’s the kind of price that tends to disappear quickly.
What makes it worth a look is the combination of serious build quality, smooth but authoritative line-stage sound, and the flexibility Octave gear is known for in revealing systems. If the condition is genuinely good, this looks like a smart buy rather than a project. I’d mainly check for age-related service history, tube wear, and whether the remote, packaging, or original paperwork are included, since those add real value at this level.
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.
