Using circuitry derived from our Apollo amplifiers, the M-180s 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.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 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. See for yourself why the M-180 monoblocks are a Stereophile Magazine "Class A Recommended Component.
