The MRE 220 SE stands as a testament to Octave's relentless pursuit of audio perfection, marking a decade of progressive innovation since the acclaimed MRE 120 made its debut. Recognized for its rock-solid reliability and exceptional audio finesse, the MRE series has consistently evolved to meet the growing demands of modern audio systems. Over the years, developments like the integration of the KT 120 power tube have significantly enhanced power reserves and bandwidth, contributing to the superior performance characteristic of the MRE amplifiers.

The MRE 220 SE is an evolution that responds to the heightened requirements of contemporary loudspeakers—devices that now offer unprecedented resolution and fidelity. Such advances in loudspeaker technology, alongside improvements in digital and vinyl playback formats, demand an amplifier capable of seamless integration and superior audio reproduction. The introduction of an adjustable damping factor in the MRE 220 SE addresses this demand, allowing users to fine-tune the amplifier to the specific requirements of their speakers, thereby optimizing sound quality across a variety of settings.

This level of flexibility is crucial, as it acknowledges the diverse power and performance needs of different loudspeaker designs. The capability of adjusting the damping factor ensures that the amplifier pairs effectively with a broad spectrum of loudspeakers, overcoming the challenges posed by the variability in their power needs and performance characteristics. Whether used in bi-amp configurations with horn systems or paired with other high-end loudspeakers, the MRE 220 SE adapts, delivering a consistently high-quality audio experience.

With options for an upgrade from the original MRE 220 to the MRE 220 SE, Octave offers a clear path for existing users to enhance their systems in line with the latest technological advancements. However, it's noteworthy that this upgrade path is currently available only within European countries. Designed with an eye for elegance, the MRE 220 SE is available in striking Silver or Black, complementing its robust technical capabilities with visual sophistication.
