WiiM Amp Pro Streaming Amplifier – Space Grey

The Space Grey WiiM Amp Pro is a network-connected stereo amplifier for passive loudspeakers. Its rated output is 60 watts per channel into 8 ohms, rising to 120 watts per channel into 4 ohms. An ESS ES9038Q2M DAC and post-filter feedback amplification distinguish it from the original Amp without changing those headline power ratings. Wi-Fi 6E, Ethernet and two-way Bluetooth provide several connection options, alongside Google Cast, Spotify Connect and TIDAL Connect. Unlike the original WiiM Amp, this model does not receive AirPlay streams. HDMI ARC brings compatible television audio into the system, with optical and analogue line inputs available for additional equipment. The HDMI connection is ARC rather than eARC, even when connected to an eARC-labelled TV port. Room correction and equalisation are controlled through WiiM Home, and a dedicated output supports an optional powered subwoofer. Passive speakers and appropriate speaker cable are needed.
