The WiiM Amp Ultra is a compact streaming amplifier that aims to combine strong sound quality with the simplicity of modern smart audio systems. For anyone looking for an alternative to the Sonos Amp from Sonos, it offers a compelling mix of features, performance, and value.
WiiM has built a reputation for making reliable, easy-to-use streaming amplifiers. These small aluminum units let you connect your TV, stream music from a wide range of services, and control everything through a stable mobile app. Just add speakers and you have a complete stereo system.
Quick Setup and Simple Design
Setting up the Amp Ultra is quick and straightforward. The box includes the necessary cables, a rechargeable voice remote, and the amplifier itself. After connecting speakers and plugging in a TV via HDMI ARC, the device displays a QR code on its 3.5-inch color touchscreen that links to the WiiM Home app for setup.
Once connected, the app manages everything from streaming services to input switching and multi-room audio. There are multiple control options including the touchscreen, remote, and the mobile app, though the app is easily the most convenient.
Features in a Compact Package
Inside the small chassis is a Class-D amplifier delivering up to 100 watts per channel, enough power for most speakers. The system uses an ESS SABRE DAC capable of high-resolution audio up to 24-bit/192 kHz.
Connection options include:
- HDMI ARC for TVs
- Optical digital input
- RCA analog input
- USB for media playback
- Ethernet
- Subwoofer output
Wireless support includes Wi-Fi 6, Google Cast, Alexa Cast, and direct streaming from services like Spotify Connect and Tidal Connect.
However, two notable features are missing: AirPlay 2 and Apple Music integration, which may matter to users heavily invested in Apple devices. There’s also no built-in phono input for turntables, meaning some setups may require an external phono stage.

Customization and Control
The WiiM Home app offers a wide range of customization options. Users can adjust EQ settings, control how inputs behave, tweak subwoofer crossover settings, and even change the display style on the front screen.
Despite the large number of options, the system remains stable and easy to use. During testing, the amplifier switched inputs quickly, streamed without interruptions, and handled TV audio reliably.
Sound Performance
The Amp Ultra delivers a noticeable improvement in sound compared to WiiM’s cheaper models. The stereo image is wider, instruments are more clearly separated, and overall clarity is improved.
Music playback sounds detailed and energetic. High frequencies lean slightly bright, but they remain smooth rather than harsh. Bass response is solid and controlled, often strong enough that a subwoofer isn’t essential depending on your speakers.
While some listeners may wish for a bit more warmth in the midrange and slightly stronger dynamics, the overall sound quality is impressive for a device in this price range.

Final Verdict
The WiiM Amp Ultra builds on the brand’s reputation for simple, reliable streaming amplifiers while improving sound quality and features. It’s an excellent option for anyone wanting a compact all-in-one stereo system that can power speakers, connect to a TV, and stream music from multiple services.
For users looking to build a modern home audio setup without complicated equipment, the Amp Ultra stands out as one of the most capable options in its category.
