The Octave HP 700 SE preamplifier has a long and successful history, with its basic circuit principles derived from the classic HP 500 model, which was introduced in 1986. This concept has been steadily developed over the past 30 years, attracting global attention.

The advanced tube technology and smart modular technology make the HP 700 future-ready from the start. The new HP 700 SE is a tube preamplifier that incorporates new precision technology and tonal output improvements. Its modular freedom meets the individual listener's need for truly personalized high-end tuning.

In the new SE version, there are two parallel XLR sockets next to the two RCA outputs on the back, allowing for all forms of bi-amping. The modifications to the actual Class-A output are the most significant, with complex measurements and accompanying listening sessions contributing to the tonal improvements.

• Precision Technology in Output: There is a circuit design that features a spectrum up to 1 MHz, low output resistance of 100 ohms, and ultra-low distortion of 0.001%. Three gain settings allow for perfect finishing.
• PSU Technology: Provides sound stability even with large voltage fluctuations. The separated power supply ensures low-noise operation.
• BYPASS: Multiple management capability for integration into an existing home theater system.
• Additional Customization Options: Modular Inputs: Two optional modular input modules for unique applications.
• PHONO: Improved design of the Phono RIAA amplifier with increased signal-to-noise ratio.
