RE 320
In the new RE 320, the successful SE technology has also been transferred to a compact stereo power amplifier. With resounding success!
Description
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.
This SE technology was previously implemented in the new Octave integrated amplifier flagship V 80 SE and is characterized by significantly increased stability and extreme linearity. As the experienced author Roland Kraft clearly stated in the test of the power amplifier in Stereoplay 03/2016: “We know of very few tube amplifiers that are so uncritical when it comes to loudspeakers and are therefore able to develop their sonic capabilities in practically any combination .” (You can read the full test here).
The concept is based on the modern KT 150 power pentodes. The extremely powerful KT 150 enable a maximum output power of approx. 2 x 130 W with two tubes in push-pull mode. The performance bandwidth of the RE 320 extends from 5 Hz to 85 kHz. The pulse power can even reach over 200 watts. This type of power development guarantees inimitable sovereignty offers enormous reserves and represents the effortless dynamics that characterize Octave.
A variety of modern and innovative detailed solutions guarantee a consistent level over the years. For example the interference signal level of more than -110 dB is so low that no hum or noise can be heard even with high-efficiency loudspeakers. Many practical features such as the fine adjustment of the BIAS the power switch for different tube types the modern ECO mode the connection for the external black box and the switchable RCA and XLR inputs make the stereo power amplifier a universal playing partner in this type of device.
The RE 320 impresses with a sound that is stable and reliable on all loads. Above all the effortlessness of music reproduction is impressive and thanks to enormous control the sound image always remains tidy believable in its dimensions and shows even the finest facets with an irresistible naturalness.
OPTIONS
Super Black Box
The Super Black Box is a passive power supply extension designed for all Octave integrated and power amplifiers. Due to the massively increased storage capacity of the power supply the pulse power of the power amplifiers is significantly increased. What is also very important is the increased independence from the electrical load – the loudspeaker. A big sonic benefit not just for sophisticated speakers.
Black Box
The Black Box is a smaller version of the Super Black Box with the same concept. It contains a circuit with electrolytic capacitors that increases the internal power supply of the amplifier and stabilizes it against mains fluctuations. Low-frequency network interference is perfectly suppressed. The black box has its own housing and is permanently connected to the amplifier using a special high-current connector.
