Liner Notes
The KSA-200S is a large stereo chassis, conservatively rated at 200 WPC into 8 ohms (23dBW). The rating continues to double down to a 1 ohm loading, where a 1600Wpc output is specified. Krell's proprietary output-stage bias system delivers dynamic class-A operation up to the maximum 8 ohm power rating, with an increasing proportion of class-AB operation with the higher current associated with lower load impedances. This "Sustained Plateau" biasing scheme is said to offer the sonic benefits of pure class-A without the massive energy inefficiency and correspondingly huge, hot heatsinks. The energy-conscious KSA-200S idles at 120W. If it ran in pure class-A, it would have to idle at around 1kW—over eight times as much wasted energy drawn from the wall.
