EVOLVED PERFORMANCE

The CXA81 Mk II isn't just a refresh; it's a reimagining. Cambridge Audio's engineers have spent countless hours tuning the circuit design and upgrading ten operational amplifiers in the post-DAC stage. This meticulous attention to detail has resulted in a sound that offers better stereo separation, lower distortion, and a more immersive soundstage. Whether it's the breath of a vocalist or the decay of a piano note, the Mk II captures the nuances that make music feel alive.

SUPERIOR DIGITAL

At the heart of the CXA81 Mk II lies the ESS Sabre ES9018K2M DAC. This high-performance chip handles digital files up to 32-bit/384kHz and DSD256 with incredible precision. It ensures that digital sources—from CD transports to streamers and laptops—are converted with a level of detail and timing that rivals standalone DACs. The result is a digital presentation that is jitter-free, spacious, and completely devoid of harshness.

FLEXIBLE CONNECTIVITY

The CXA81 Mk II is designed to be the hub of your hi-fi system. It features a wide array of connections, including balanced XLR inputs for the best possible analogue performance, four RCA analogue inputs, and multiple digital inputs (TOSLINK, Coaxial, and USB Audio). The built-in Bluetooth aptX HD receiver adds modern convenience, allowing you to stream high-quality audio directly from your smartphone or tablet without the need for extra dongles or boxes.
