Cambridge Audio CXA81 Mk II Integrated Stereo Amplifier

Cambridge Audio CXA81 Mk II integrated stereo amplifier

The Cambridge Audio CXA81 Mk II is a refined integrated amplifier designed to deliver high-resolution audio performance with enhanced clarity, depth, and control. Building upon a multi-award-winning platform, this model introduces upgraded internal components and circuit refinements while maintaining its established dynamic and engaging sound signature.

At its core, the CXA81 Mk II features an ESS Sabre ES9018K2M digital-to-analog converter, supporting high-resolution audio formats up to 32-bit/384kHz PCM and DSD256. The re-engineered analog stage incorporates improved operational amplifiers, reducing distortion and enhancing signal accuracy for both digital and analog sources. This results in a more defined, detailed, and balanced listening experience across a wide frequency range.

Delivering 80 watts per channel into 8 ohms, the amplifier is capable of driving a variety of speakers with authority and precision. A large toroidal transformer ensures stable power delivery and dynamic headroom, enabling consistent performance even during demanding audio passages.

Connectivity options are extensive, including balanced XLR, multiple RCA inputs, optical and coaxial digital inputs, and asynchronous USB. Integrated Bluetooth with aptX HD support allows high-quality wireless streaming, while Roon Tested certification ensures compatibility with advanced digital audio ecosystems.

Outputs include speaker terminals, a pre-out, subwoofer output, and a headphone connection, offering flexibility for different system configurations. Encased in a minimalist Lunar Grey chassis, the CXA81 Mk II combines refined engineering, modern connectivity, and high-fidelity performance for demanding audio systems.
