Power, Grace, and Precision—when you are ready for these “ultimates” in vacuum tube amplification, look no further than the M-180. With 180 Watts of pure tube power, these monoblocks stunningly accomplish the impossible. After they draw the curtains aside on a soundstage which is unprecedented in height, width, and depth, these monoblocks’ pace and musicality provide a riveting performance that will leave you breathless. And along with their profound sonic merits, the M-180 are aesthetically exquisite amplifiers that will stoically serve as the cornerstones of your system.
Using circuitry derived from our Apollo amplifiers, the M-180 are marked by an exceptional design that places it squarely at the forefront of tube technology. Just a few of the notable features are a “slow start” logical turn-on for extended tube life, a massive high capacity power supply, and the ability to externally switch between either ultra-linear or pure triode operation mode. The highly efficient design also means cool running and greatly extended tube life. Other refinements include balanced (XLR) and RCA inputs, mechanically isolated transformers, matched octets of KT120 output tubes, and separate 4 Ohm and 8 Ohm taps on the rear. In keeping with Rogue Audio’s “quality by design” philosophy, only the finest components are used in the construction of these remarkable amplifiers.
