Overview

An integrated Class AB stereo amplifier provides 80 Watts RMS per channel into 8 Ohms and utilizes an ESS Sabre ES9018K2M DAC. Built with optical, coaxial, USB, and balanced XLR inputs, it offers premium audio visual solutions for a high performance home sound system setup.

The Cambridge Audio CXA81 Mk II integrated stereo amplifier serves as a stable, high performance foundation for a traditional home sound system setup. Engineered and acoustically optimized at the London based workshop and headquarters, this revised layout introduces ten new premium components to the amplification circuitry and optimizes the signal path to resolve clarity and musicality issues during playback.

The core amplification architecture uses a Class AB design paired with a heavy toroidal transformer, delivering eighty Watts root mean square per channel into eight Ohm loads or one hundred and twenty Watts into four Ohms. This power configuration supplies enough current to confidently drive demanding speaker designs. Digital to analog conversion is managed by an upgraded onboard ESS Sabre ES9018K2M reference level digital to analog converter. Physical digital inputs include optical TOSLINK, S S/PDIF coaxial, and a USB audio port that processes up to twenty four bit three hundred and eighty four kilohertz pulse code modulation files alongside native DSD256 signals. Analog sources connect via four pairs of RCA inputs or a balanced XLR stereo input, which matches the companion CXN100 network player. Wireless connectivity relies on an integrated Bluetooth receiver supporting the aptX HD profile for high quality streaming from compatible devices like a turntable.

The metal enclosure measures one hundred and fifteen by four hundred and thirty by three hundred and forty one millimeters and weighs nineteen point one pounds. Running at full capacity, the unit draws a maximum of seven hundred and fifty Watts, while the standby configuration drops energy consumption below half a Watt. A system remote control is included to complete this Roon tested audio component, providing flexible operational control within clean audio visual solutions.
