Product Description

the Orchestral

Our perennial preamplifier, the HP 500, has been around for almost as long as OCTAVE and was in many ways responsible for defining our approach to building amplifiers. For over 20 years, this preamplifier has been the epitome for consistent excellence in sound quality and state-of-the-art tube technology.During this time, it has maintained its market-leading position thanks to regular design updates from OCTAVE.

OCTAVE recently developed the SE (Special Edition) version to mark the 25th anniversary of Stereoplay magazine, which first tested the original HP 500 in 1989. The SE brings the HP 500 preamp back to the current state-of-the-art once more. The use of two Siemens D3A (EF 184) pentodes provides the output stage of the HP 500 SE with a significantly greater bandwidth (0.2 Hz to 2.3 MHz, 6 dB).

The extremely low cut-off frequency is responsible for the clearer and more tightly defined bass, which provides the foundation for a clean low frequency register and a thrilling midrange performance. OCTAVE has also further refined the outboard power supply. MOSFET transistors regulate the high-voltage supply. Increased reservoir capacity, improved rectification with Schottky diodes, and end-to-end electronic stabilization all ensure a virtually noise-free supply voltage with a noise component of less than 300 µV. These measures contribute to the exceptionally high signal-to-noise ratio of 103dB.
