About the KSA-300S
The Krell KSA-300S is a premium solid-state stereo power amplifier introduced in 1994. It is celebrated for its ability to deliver 300 watts per channel into 8 ohms, with power output doubling as impedance is halved down to 1 ohm. The amplifier features a wide frequency response, low distortion, and a high slew rate, making it suitable for demanding loudspeaker loads. Its five bias levels ensure pure Class A operation according to the input signal, from idling to maximum output. The KSA-300S is praised for its detailed, neutral sound signature, robust bass, and world-class fit and finish.
