Reference-level pure tube monoblocks • over 250 watts in Ultralinear mode • selectable Triode/Ultralinear operation • balanced and RCA inputs • built in bias meters • entirely designed and built in the USA
The Rogue Audio M-250 Ultra Monoblock Amplifiers represent the company’s flagship approach to reference-level tube amplification, combining elegance, refinement, and immense output capability in a true monoblock platform. Designed to reveal the finest musical details while delivering seemingly limitless dynamics, these amplifiers are built for listeners who want the tonal sophistication of tubes without sacrificing authority, scale, or control.
Whether the system is centered around jazz, rock, or large-scale orchestral works, these amplifiers are engineered to combine clarity, bandwidth, and dynamic authority at a truly serious level.
Pure tube amplification platform — each amplifier uses six KT88 output tubes, along with two 12AU7 tubes and one 12AX7, to deliver high continuous power with the dimensionality, texture, and natural harmonic character that tube enthusiasts value.
Ultra-high performance transformers — large transformers and ultra-high tolerance parts contribute to the amplifier’s bandwidth, dynamic range, and exceptionally stable overall performance.
Flexible connectivity and speaker matching — the rear panel includes balanced XLR and single-ended RCA inputs, plus both 4 and 8 ohm binding posts for easier integration into a wide range of serious two-channel systems.
In a carefully assembled reference system, the Rogue Audio M-250 Ultra Monoblock Amplifiers deliver the kind of scale, composure, and musical openness expected from statement-level tube amplification.
