About the SA-50 mkIII
The Plinius SA-50 mkIII is a solid-state stereo power amplifier rated at 50 watts per channel into 8 ohms and 100 watts per channel into 4 ohms, with the same power rating whether operated in class A or class AB mode. It features a front-panel switch that allows the user to select pure class A or class AB operation, offering the smoother, more refined character associated with class A along with the higher efficiency and cooler running of class AB. The SA-50 mkIII can also be configured for bridged mono operation, in which a single unit is used as a high-power mono amplifier, a capability consistent with the SA-50 platform's design. Connectivity includes both single-ended (RCA) and balanced (XLR) inputs, and the amplifier is widely praised for its robust construction, stable drive into demanding loudspeaker loads, and clean, detailed, and musical sound quality in high-end HiFi systems.
