Octave MRE 220 SE Power Amplifier

The Octave MRE 220 SE represents the latest evolution of Octave’s legendary mono power amplifier series. Building on over three decades of refinement—from the MRE 120 through the MRE 130 and the original MRE 220—the SE version is designed to meet the demands of modern high-resolution loudspeakers and today’s uncompromising playback sources.

At its core, the MRE 220 SE employs the powerful KT 120 output tube, delivering impressive power reserves, extended bandwidth, and exceptional reliability. What sets the SE apart is its adjustable damping factor and variable negative feedback, accessible via chassis-mounted switches. With “LOW” and “HIGH” damping factor settings, listeners can tailor the amplifier’s performance to perfectly match the requirements of their loudspeakers—whether high-efficiency horn systems, low-impedance designs, or modern high-resolution speakers. This flexibility ensures a seamless synergy, resulting in a wide, spacious soundstage, a richly resolved midrange, and a silky, natural tonal balance.

In true Octave tradition, the MRE 220 SE integrates advanced engineering solutions for both performance and durability. Its redesigned output stage and proprietary transformer technology guarantee stability across a wide range of loads, while ultra-low noise levels maintain complete clarity even with the most sensitive loudspeakers. Power management with soft-start electronics, comprehensive protection systems, Eco Mode, bias control and display, and compatibility with Octave’s Black Box and Super Black Box upgrade modules ensure long-term reliability and user convenience.

With its combination of authority, finesse, and adaptability, the MRE 220 SE is a modern classic—an amplifier that maintains Octave’s reputation for rock-solid reliability while offering unprecedented flexibility for today’s diverse and demanding loudspeaker landscape.
