About the CXA81 II
The Cambridge Audio CXA81 II (also styled CXA81 Mk II) is a two-channel Class AB integrated stereo amplifier with a built-in ESS Sabre DAC, Bluetooth aptX HD reception, balanced XLR connectivity, and high-resolution USB audio. It delivers 80 watts per channel into 8 ohms and 120 watts per channel into 4 ohms, and uses a toroidal power transformer intended to provide substantial current delivery for a broad range of loudspeakers. The Mk II revision replaces the original CXA81’s DAC with an ESS ES9018K2M SABRE32 device and supports PCM up to 32-bit/384 kHz plus DSD256 over USB.
