WiiM has become a go-to name for bringing high-resolution streaming to any sound system, from the simplest setup to the most fully equipped one. The lineup now includes four models: the WiiM Pro Plus, WiiM Ultra, WiiM Amp Pro, and WiiM Amp Ultra, each built for a different need. All four run on the same WiiM Home app, where the equalizer, multiroom settings, and streaming service connections live, making it easy to move between models once you know the brand. This guide helps you figure out which one to choose based on the gear you already have at home and how you plan to use the system.
Already have an amplifier: WiiM Pro Plus or WiiM Ultra
If you already have an amplifier or a working sound system, all you need is to add quality streaming. That's where the WiiM Pro Plus and the WiiM Ultra come in, two streamers with a built-in DAC that connect to the line input of your existing amplifier. Neither one amplifies sound on its own, which means the final sound quality also depends on the amplifier and speakers already in place. Choosing between them comes down to the level of gear you want and your budget.
The WiiM Pro Plus uses an AKM DAC and supports Hi-Res audio up to 24-bit/192kHz, with analog RCA, optical, and coaxial outputs. It's the most straightforward option for anyone who wants AirPlay 2, Chromecast Audio, Spotify Connect, and Tidal Connect without a big outlay.
The WiiM Ultra steps things up: it has an ESS Sabre DAC, a 3.5-inch touchscreen showing album artwork, a phono input for a turntable, a line input, HDMI ARC for the TV, and a subwoofer output. It suits anyone who wants to bring together vinyl, TV, and streaming in one device before sending the signal on to the amplifier.

Amplifier and streaming in one device: WiiM Amp Pro or WiiM Amp Ultra
If you're starting from scratch or want to simplify your system, you can choose an amplifier with built-in streaming, doing away with a separate amplifier and cutting down on the number of devices and cables near the speakers. The WiiM Amp Pro delivers 60W per channel at 8 ohms (120W at 4 ohms) with an ESS Sabre DAC, HDMI ARC, and a subwoofer output, enough to drive a pair of passive speakers in medium-sized rooms.
The WiiM Amp Ultra tops the range: 100W per channel at 8 ohms with ultra-low distortion, a 3.5-inch touchscreen, and RoomFit room correction, which tunes the frequency response to the space where the system is set up. It also has HDMI ARC, a subwoofer output, and a remote control included.
TV, turntable, and room tuning
HDMI ARC is available on the WiiM Ultra, the WiiM Amp Pro, and the WiiM Amp Ultra, letting you bring the TV's sound to the system's speakers without extra cables or remotes. Only the WiiM Pro Plus misses out on this feature.
For anyone with a turntable, the WiiM Ultra is the only one of the four models with a dedicated phono input, making it the natural choice for bringing vinyl and streaming together in one device.
RoomFit room correction, meanwhile, is reserved for the WiiM Amp Ultra, the model best suited to anyone who wants to tune the sound to their room without extra outboard gear.
When it comes to music services, all four models share the essentials: AirPlay 2, Chromecast Audio, Spotify Connect, and Tidal Connect, plus multiroom with other WiiM devices through the WiiM Home app. That's why the choice between them mostly comes down to the physical connection you need (amplification, HDMI ARC, or a phono input) rather than the streaming services supported, which are the same across the whole lineup.

Frequently asked questions
Do the WiiM Pro Plus and WiiM Ultra amplify sound?
No. Both are streamers with a built-in DAC and no amplification of their own, designed to connect to the line input of an existing amplifier or sound system. To combine amplification and streaming in a single device, the options are the WiiM Amp Pro and the WiiM Amp Ultra.
Which model should I choose to connect the TV over HDMI ARC?
The WiiM Ultra, the WiiM Amp Pro, and the WiiM Amp Ultra all have HDMI ARC, letting you receive the TV's sound directly through the system's speakers. The WiiM Pro Plus does not have this connection.
Which model has RoomFit room correction?
Only the WiiM Amp Ultra includes RoomFit room correction, which adjusts the amplifier's frequency response to the space where the speakers are placed.
Before deciding, it's worth understanding the difference between a DAC and a streamer, and whether streaming replaces vinyl outright or the two can happily coexist in the same system. The guides DAC and streamer explained: do you need one? and Vinyl or streaming help clear up these questions before you buy.
