The Amp Pro is the quiet one. WiiM took the original Amp platform and rebuilt the signal path around an ES9038 SABRE DAC and post-filter feedback amplification, so background hiss sits far below the music even on sensitive speakers.
It suits a lounge where television and music share the same pair of speakers. HDMI ARC accepts Dolby Digital 5.1 soundtracks from the TV, and a dedicated output hands the low end to a subwoofer when the room has one.
Control runs through the WiiM Home app, with Alexa and Google Assistant both supported, and the upgraded wireless platform keeps streaming stable even in a flat full of competing networks.
