Angeboten wird „HP 300 SE“ von Octave als Gebrauchtgerät aus der Kategorie „Vorverstärker / Prozessor“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 9400747031 endet am 18.08.2026 um 07:24 Uhr.
This is a fair ask, slightly above the market but still close enough to be reasonable. Against your own EUR comparables, €5,800 sits above the €5,613 median and just over the €5,696 75th percentile, so it reads as a mild premium rather than a bargain or a stretch.
That premium makes sense if the unit is genuinely clean and well cared for, because the HP 300SE is a respected preamp with a strong reputation for transparency, drive, and long-term musical ease. At this level, the buy case is strongest when the seller can show tidy cosmetics, solid service history, and complete original accessories; if those boxes are checked, it’s still an appealing piece for someone who wants a serious analog front end without moving into true “collector tax” territory.
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.
