The Cambridge Audio CXA81 amplifier is an ideal compliment to your preamp or AV receiver. The benefit of a separate amplifier is that you will get true high fidelity sound without distortion and unwanted noise.

Power Features

This two-channel amplifier is intended to feed 80 watts RMS at 8 ohms resistance to your speakers. It works fantastically well for providing power to floor standing speakers with high power demands. Power comes from an overspecified toroidal transformer that ensures each value is accurately presented at any volume level.

Optimized capacitor values provide you with the clarity and control of frequencies that you demand without overtaxing the amplifier. Sound quality is nearly free of unwanted noise that frequently appears in preamp systems due to the close proximity of the preamp and amplifier functions. With this separate, you’ll experience the entire range of audio as your music was meant to be heard.
