Angeboten wird „HP-300 MK2 Röhrenvorstufe“ von Octave als Gebrauchtgerät aus der Kategorie „Vorverstärker / Prozessor“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 8919367365 endet am 26.06.2026 um 06:30 Uhr.
Good buy if the condition is genuinely clean: €2,200 for a working HP-300 MK2 with cables/accessories sits in the attractive part of the used market, and it looks competitive versus recent asking prices around €1,990 for an HP-300 and roughly €2,950 for another HP-300-class listing. That makes this feel more like a fair-to-strong deal than an ambitious one, especially if it’s fully functional and well cared for.
The appeal here is classic Octave: a highly regarded tube preamp with a big, composed, low-fatigue presentation and enough refinement to stay in serious systems for years. The extra cables/accessories add real value, and the MK2 has the right long-run reputation to make this a sensible buy for someone wanting a premium valve line stage without paying new-money Octave pricing.
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.
