A streaming amplifier that drives passive speakers directly. The WiiM Amp Ultra delivers 100 W per channel into 8 ohms or 200 W per channel into 4 ohms, with a 3.5 inch touchscreen, HDMI ARC, optical and line inputs, a subwoofer output and RoomFit room correction.

WiiM says the Amp Ultra is built to give bookshelf, tower, in-wall or outdoor passive speakers more power and control, and to bring TV, a turntable and streaming services into one hi-fi system. You control it from the touchscreen, the WiiM Home app or the supplied WiiM Voice Remote 2.

Why you will love it

Power for your passive speakers

The Amp Ultra uses two TI TPA3255 Class-D amplifiers with Post-Filter Feedback. WiiM rates it at 100 W per channel into 8 ohms and 200 W per channel into 4 ohms, and lists a speaker impedance range of 2 to 8 ohms.

Speaker connections are gold-plated binding posts that take banana plugs or bare wire. Four banana plugs are in the box.

See what is playing

The 3.5 inch touchscreen shows album art and playback controls, and lets you switch inputs and outputs, adjust EQ and open smart presets. A rotary knob on the front handles volume and play/pause.

The chassis is machined from a single piece of aluminium. WiiM lists a copper heat pipe, a large aluminium heatsink and PID thermal control, with passive, silent cooling.

RoomFit and EQ

RoomFit room correction helps adapt playback to the acoustics of your room. You can also start from one of 24 EQ presets, use a 10-band graphic EQ or a 10-band parametric EQ, and set EQ per source so a turntable, TV and streaming service each keep their own tuning.

TV, turntable and streaming in one

Connect a TV by HDMI ARC or optical. WiiM lists Stereo PCM and Dolby Digital support on both, and says DTS is not supported. A turntable or CD player connects to the line input, and the Amp Ultra can play files from USB storage.

For streaming, WiiM lists Google Cast, Spotify Connect, TIDAL Connect, Amazon Music casting, DLNA, QPlay 2.0, Squeezelite and Roon Ready. The WiiM Home app adds services such as Spotify, Amazon Music, Deezer, TuneIn, TIDAL, Qobuz and SoundCloud. WiiM says availability varies by service, plan and region.

Subwoofer, multiroom and home theatre

A subwoofer output lets you add a powered subwoofer, and you set it up in the WiiM Home app. WiiM also suggests pairing it with the WiiM Sub Pro.

Group WiiM devices for synchronised playback, make a stereo pair, or use your speakers as the front left and right channels of a WiiM 5.1 home theatre over HDMI. WiiM says physical inputs such as line-in, optical, HDMI ARC and Bluetooth can only be shared in a group made entirely of WiiM devices.

Is it right for you?

A great fit if you…

Want to stream to passive speakers without separate components
Want to add TV sound through HDMI ARC to a stereo system
Have a turntable or CD player to connect to the line input
Want room correction and detailed EQ
Plan to add a powered subwoofer

Worth knowing

It has no AirPlay 2 support. WiiM lists Google Cast, Spotify Connect, TIDAL Connect, Roon Ready and DLNA
It has no built-in phono input, so a turntable needs a built-in or external phono preamp
DTS is not supported over HDMI ARC or optical
WiiM says it works with Alexa and Google, but not Siri

Build your system

Speakers: Pair with bookshelf speakers or floorstanding speakers
Stands: Add speaker stands for bookshelf speakers
Bass: Use the subwoofer output with a subwoofer
Turntable: Connect a turntable with a built-in phono preamp to the line input
Other WiiM: Compare the WiiM Amp Pro and the WiiM Amp, or see the WiiM range
