The WiiM Amp Pro builds on the original Amp with upgraded wireless connectivity and audio components, while retaining its compact all-in-one streaming amplifier design. Its Class D amplification delivers 60W per channel into 8 ohms or 120W per channel into 4 ohms, with an ESS ES9038 Q2M DAC and improved signal-to-noise performance. Wi-Fi 6 connectivity, Bluetooth 5.3 and Ethernet provide flexible network access, while support for Google Cast, Spotify Connect, TIDAL Connect, Roon Ready and DLNA makes it easy to stream music from a wide range of services and devices.
Designed to power passive loudspeakers, the Amp Pro also includes HDMI ARC, optical and analogue line inputs, USB playback and a dedicated subwoofer output. Its adjustable EQ and room correction options allow the sound to be tailored to the room and connected speakers, while multi-room functionality makes it possible to group playback with compatible WiiM devices. Unlike the standard Amp, the Amp Pro does not support AirPlay 2.
