About the CA-100
The Classe CA-100 is a stereo power amplifier known for its high current output and sleek curved chassis design with large dual heat sinks at the rear. It delivers 100 watts per channel into 8 ohms in stereo mode and up to 350 watts into 8 ohms in mono mode. The amplifier supports both regular and balanced inputs, which are externally switchable but cannot be used simultaneously. It features a frequency response of 20 Hz to 20 kHz with a total harmonic distortion of 0.03%, a gain of 29.02 dB, and a signal-to-noise ratio of 128 dB. The amplifier is designed to drive speaker loads down to 4 ohms minimum. It weighs 34 lbs and measures 19 x 14.25 x 5.5 inches. The CA-100 is available in satin black or soft shadow silver finishes and includes protection circuitry with rail fuses to protect output drivers. An optional remote control interface is also available. The unit is no longer in production but remains highly regarded for its sound quality and build.
