 Octave RE 320 Power Amplifier 


In the new RE 320, Octave’s SE-technology has been effectively implemented into a most astonishing compact stereo power amplifier - with resounding success!

The Octave RE 320 stereo power amplifier marks a significant evolution of this model series. The heart of the amplifier, the actual amplifier stage, is completely revised. Because for the first time the technical details of the Jubilee SE models have been utilized.

Together with a specially developed power supply for the SE-concept, as well as highly specialized, wideband transformers, the RE 320 can drive almost any speaker on the planet and always plays -unaffected by the load - at the same extremely high performance level.

This SE technology, previously implemented in the new Octave V 80 SE flagship integrated amplifier model, is characterized by significantly enhanced stability and extreme linearity.

As the experienced author Roland Kraft has carved out unambiguously in the review of the RE 320 in the German hifi magazine Stereoplay 03/2016: "We know very few tube amplifiers that are so uncritical in terms of speakers and therefore are able to unfold their sonic capabilities in virtually any combination.”(Please click here to access the complete review)

The concept is based on the modern KT150 power pentodes. The extremely high current of the KT150 allows a maximum output power of about 2 x 130 W with two tubes in push-pull mode.

The frequency range of the RE 320 extends from 5 Hz to 85 kHz. Looking to the impulse power, the 320 can achieve over 200 watts. This type of power delivery guarantees an inimitable sovereignty, with huge reserves while perfectly representing the effortless dynamics that distinguishes Octave.

A variety of modern and innovative detail solutions ensures a constant performance level that will last for years. Thus, for example, the noise level is so extremely low - by more than -110 dB, that even with high efficiency loudspeakers no hum or noise is heard.

Many practical features such as the precise adjustment of the BIAS, the power switch for different tube types, the intelligent ECO mode, the optional connection for the external black box modules and the switchable RCA and XLR inputs make the RE 320 stereo power amplifier a universal playback partner in this component category.


The RE 320 enchants with a sound that is stable and reliable at all loads. The ease of musical playback is particularly impressive and thanks to the incredible control the sound always remains composed, honest in its dimensions and conveys even the finest details with an irresistible naturalness.
