80 watts a channel of Class AB with a proper DAC inside.
Cambridge re-engineered the signal path of the original CXA81 with premium parts end to end and an upgraded DAC. A large toroidal transformer with dual taps into the left and right of the amp board gives each channel its own supply.
Digital sources connect over optical, coaxial and USB Audio, analog sources over RCA or balanced XLR, and phones over Bluetooth aptX HD. A second set of speaker outputs covers another room. It is Roon Tested.
