Our SA Series Amplifiers are the latest models in a product line that spans almost four decades. On the test bench, they “doubled down”, increasing power output as the impedance load dropped. Though our new SA Series mono amplifiers output stability aren’t rated into loads less than 1 ohm, their current-feedback output-stage is designed to remain stable into 0.6 ohm loads. These newest “Beasts” are very compact, but don’t let their size fool you. They all pack a serious punch.
