Offered is „HP 700“ by Octave as second-hand device from the category „Tube-Preamp“ on audio-markt.de - the online market place for high-end. The advert with the number 5469406267 ends on 02.11.2026 at 17:37 o'clock.
Is €7,900 a fair entry point for the Octave HP 700, or is it stretching the budget? This asking price sits just below the 75th percentile of €8,108 and is comfortably above the median of €5,798, making it a fair but not bargain deal for a used unit in good condition. It is notably lower than current new prices for the HP 700 SE (€12,000–€14,200), offering solid value for a well-regarded modular tube preamp.
The HP 700 is prized for its ultra-low distortion (0.001%), extremely low output resistance (100 ohms), and flexible modular design with external power supply, delivering clean, detailed sound with three gain settings. At €7,900, this is a worthwhile buying opportunity for enthusiasts seeking high-end tube performance without the new-model cost, especially if it includes original accessories and shows no signs of age-related wear.

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.
