Build a versatile stereo system around the Cambridge Audio CXA81 Mk II. Integrated amplification and a built-in DAC bring speaker power and digital connectivity together in a single component with room for multiple sources.

Key Features

  • Custom Class AB amplification – blends Class A warmth with Class B efficiency, and a short signal path keeps added coloration to a minimum.
  • 80 watts per channel – a toroidal transformer with dual taps supplies the power, so loud peaks and quiet passages both stay controlled.
  • ESS ES9018K2M DAC – plays digital files up to 32-bit/384kHz and DSD256 straight from your computer over USB.
  • Bluetooth aptX HD – stream from your phone at high quality without extra hardware.
  • Balanced XLR inputs – connect sources with balanced outputs for a clean, low-noise link.
  • Second speaker output – run another pair of speakers so music can reach a second room.

Good to Know

The amplifier is Roon Tested, so it slots into an existing Roon setup via a simple USB connection to a PC or Mac. The aluminum and steel case keeps the front panel to power, input selection and a smooth volume control.
