A compact network streamer with an AKM AK4493SEQ DAC for the analog output. The WiiM Pro Plus lists 121 dB SNR and -113 dB THD+N on its RCA line out, with optical and coaxial outputs, AirPlay 2, Google Cast, Roon Ready, RoomFit and a Voice Remote in the box.
WiiM says to choose the Pro Plus when you plan to use the RCA line out and want its premium analog performance in this compact form. It is a streamer, not an amplifier, and is set up with the WiiM Home app.
Why you will love it
AKM DAC and analog stage
WiiM says the AKM AK4493SEQ DAC, an ultra-low-noise clock and an optimised power and signal path give 121 dB SNR and -113 dB THD+N through the line out. Frequency response is listed as 20 Hz to 20 kHz (plus or minus 0.1 dB).
Analog input is converted by a TI Burr-Brown PCM1861 ADC at up to 192 kHz, 24-bit.

Streaming for the system you own
Connect it to an amplifier, receiver or powered speakers through RCA, or send bit-perfect digital audio to an external DAC through optical or coaxial output, up to 24-bit/192 kHz. For bit-perfect output WiiM says to enable Fixed Volume and disable EQ and mono audio.
WiiM lists AirPlay 2, Google Cast, Alexa Cast, Spotify Connect, TIDAL Connect, DLNA and Roon Ready. Service availability and quality vary by service, plan, region and source.
Voice Remote and 12 V trigger
The included Voice Remote handles playback, volume, inputs, four presets and push-to-talk voice commands. Front touch controls cover the essentials.
A 12 V trigger output (2.5 mm jack, with a converter in the box) can wake a compatible amplifier or DAC, and input auto-sensing switches to Line In or Optical In when a signal starts.
Tuning, multi-room and other sources
RoomFit room correction, 24 EQ presets, a 10-band graphic EQ, a 10-band parametric EQ and per-source EQ are in the WiiM Home app.
Share Line In, Optical In and Bluetooth sources across a group of WiiM devices. WiiM says Alexa and Google groups carry network streams only, and the Pro Plus does not send physical inputs into an AirPlay group.
Is it right for you?
A great fit if you…
- Want to add streaming to an amplifier, receiver or powered speakers you already own
- Want AirPlay 2, Google Cast, Spotify Connect, TIDAL Connect and Roon Ready in one box
- Want optical and coaxial digital outputs for an external DAC
- Plan to add more rooms with other WiiM devices
- Want the upgraded analog output and analog input of the Pro series
- Want a remote and 12 V trigger included
Worth knowing
- It is a streamer and has no amplifier, so it needs an amplifier, receiver or powered speakers
- WiiM says if you will always use an external DAC, the WiiM Pro may already cover your streaming needs
- Optical input takes stereo PCM only (no Dolby Digital or DTS)
- The USB-C port is for power only, not USB storage or USB audio
- Wi-Fi is dual-band 802.11 b/g/n/ac and Bluetooth is 5.0
Build your system
The WiiM Pro Plus connects to the amplifier or powered speakers you already have. If you are starting from scratch, these are good places to look.
- Amplification: Connect to a stereo amplifier or AV receiver through the RCA line output
- Speakers: Pair the amplifier with bookshelf speakers or floorstanding speakers
- Turntable: Connect a turntable with a built-in phono preamp, or add an external phono preamp, to the line input
- Other WiiM: See the WiiM Ultra streaming hub, the WiiM Amp Pro streaming amplifier, the WiiM Pro Wi-Fi audio streamer or the full WiiM streamers and amplifiers
