The HP 300 SE is a preamplifier from Octave Audio, a well-established German manufacturer known for accomplished tube-informed electronics engineering, built with comprehensive two-plus-three input connectivity and an exceptionally wide bandwidth. The HP 300 SE brings Octave's considered engineering to dedicated line-level signal control.
Key specs that matter
Two balanced XLR inputs and three single-ended inputs are provided, with one balanced and two single-ended outputs. Gain is 25dBu. Frequency response spans a wide 10Hz to 200,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 92dB unweighted, with total harmonic distortion plus noise under 0.005%. At 438 x 78 x 390mm and 9kg, the HP 300 SE maintains a manageable preamplifier chassis reflecting Octave's considered German engineering standards.
Sound and use context
Expect the warm, considered character Octave's broader tube-informed engineering philosophy is celebrated for, with the wide 10Hz-200kHz bandwidth combined with the exceptionally low 0.005% distortion figure.
Pairing
Octave's own power amplifier catalogue offers natural, brand-coherent pairings within the same broader catalogue.
Alternatives
Other manufacturers' comparable tube-informed preamplifiers offer alternatives for buyers wanting to compare features at a similar price point.
