The WiiM Amp Ultra provides 100 watts per channel from a class-D amplifier using dual TI TPA3255 chips, paired with an ESS Sabre DAC for low-distortion, high-clarity audio. This combination handles dynamic swings in orchestral music and keeps dialogue clear in movies. The front touchscreen shows album art and input status, offering satisfying local control without needing the app.
Built-in RoomFit room correction uses your phone's microphone to measure your space and adjust frequency response, including subwoofer crossover and level. It effectively tames boomy bass in awkward rooms. HDMI ARC simplifies TV audio: one cable carries sound from the TV and enables the amp to power on with the TV remote. Optical and RCA inputs allow connection of CD players or other legacy sources.
The companion app guides you through initial setup, Wi-Fi connection, and streaming service login in a few minutes. Multi-room grouping with other WiiM devices is flexible. Occasional connectivity drops with Pandora and SoundCloud have been noted, but core streaming via Tidal, Amazon Music, or Spotify Connect remains stable. The app receives regular updates that address such edge cases.
This amplifier is for streaming music enthusiasts who want a modern all-in-one system that also serves as a TV soundbar replacement. It lacks Apple AirPlay, so if you primarily stream from an iPhone, consider the WiiM Amp Pro (which includes AirPlay 2) or a different source. For Android users and multi-room devotees, the Ultra offers a rare mix of high-end DAC, room correction, and robust power at a premium but competitive price.
Tip: If you use Pandora or SoundCloud frequently, test the connection during the return period to ensure stability.
Bottom line: The WiiM Amp Ultra is the integrated amplifier for listeners who want streaming, room correction, and TV integration in one box — as long as AirPlay isn't required.
