If you have a sound system that you love and want to modernize it to enjoy High-fidelity streaming with AndroidThe Wii U Pro and Wii U Pro Plus are two compact solutions that add AirPlay 2, Chromecast Audio, Spotify Connect, TIDAL Connect, Alexa Cast, and multi-room audio to almost any system. In this guide, we'll explain in detail and in Spanish, everything you need to know to choose between the two, get the most out of them with your Android phone, and understand their key differences.
Beyond marketing, the grace of these streamers is that turn your stereo into a smart system Without having to replace expensive speakers, amps, or cables. With the Wii Home app, you can centralize your music services, customize the sound for your room, and control multiple devices simultaneously—whether via Wi-Fi, Ethernet, or Bluetooth—and with voice assistants like Alexa, Google Assistant, or Siri.
What WiiM Pro and WiiM Pro Plus bring to your setup
The approach is simple: you plug the WiiM into your network and your amplifier/speakers, and you get a receiver compatible with AirPlay 2, Chromecast Audio, DLNA and Connect modes from Spotify and TIDAL. So you can play from your favorite apps, from the Wii U Home app, or using your voice, with multiroom support to sync music across multiple rooms.
The proposal is especially attractive for audiophiles and music lovers because the WiiM Pro Plus reinforces the analog and digital part: it integrates a Next-generation AKM 4493SEQ DAC, an ultra-low noise clock and a premium ADC to digitize analog sources with great clarity. All with seamless playback and advanced equalization for adjust the sound profile to your liking.
Differences between WiiM Pro and WiiM Pro Plus
Although both models share most of the network and control functions, the Wii Pro Plus adds internal improvements designed to maximize audio quality. Specifically, it incorporates a AKM 4493SEQ DAC with Velvet Sound technology, capable of handling up to 768 kHz/32-bit and DSD512, with SNR figures of 120 dB (A‑wt) and THD+N of -110 dB at 1 kHz, resulting in a more transparent analog output.
On the analog input side, the Pro Plus uses a TI/Burr‑Brown PCM1861 ADC It converts to digital up to 192 kHz/32-bit and achieves a signal-to-noise ratio of 110 dB. This is useful if you connect a turntable with a preamp, an MP3 player, or TV audio to the line input to integrate them into your network and multiroom scenarios.
There is also special care in the design: the Pro Plus employs Low-noise clock, optimized power supply and PCB with paths and power supply treated to minimize distortion. Analog output performance points to a THD+N below -110 dB, a remarkable figure for its price and size range.
Connectivity, protocols and control
Both WiiMs offer dual-band Wi-Fi (IEEE 802.11 b/g/n/ac), 100M Ethernet for maximum stability and Bluetooth 5.1. Bluetooth is bidirectional on the Pro Plus: it can act as both a receiver and a transmitter to send sound to compatible Bluetooth headphones or speakers.
In casting and control protocols, the list is extensive: AirPlay 2, Chromecast Audio, DLNA, Spotify Connect, TIDAL Connect and Amazon Music Casting/Alexa CastAdditionally, they integrate with voice assistants (Alexa, Google Assistant, and Siri) and are compatible with HomePod, Echo devices, and Google Home in multi-room settings.
The multiroom experience is agnostic: you can play music on multiple devices at once from WiFi, Bluetooth sources or physical inputs (Aux/SPDIF)This is especially useful if you pair a Wii with smart speakers or if you have multiple WiiMs scattered around your home.
The Wii Home app: all in one app
The Wii U Home app centralizes your music and device settings in one place. In its Favorites tab, you have quick access to your most listened to playlists, stations, and tracksYou can save stations and explore new artists. The goal is to avoid having to jump between multiple apps to find what you're looking for.
Another strong point is multi-room control: from anywhere, you can organize what plays in each room or synchronize the entire house with the same song. The app automatically detects nearby WiiUs, which facilitates stereo pairing, creating a surround system and adding devices to extra rooms with just a few taps.
To adjust the sound, the app includes Integrated EQ and Room Correction to adapt the response to your tastes and environment. You can also set musical alarms and custom routines to automate scenes with Alexa, Apple Home, or Google Home.
Streaming services and sources
WiiMs natively integrate services such as Spotify, Amazon Music, Deezer, TuneIn, TIDAL, Qobuz, SoundCloud, Pandora, iHeartRadio, Napster, SoundMachine or Calm Radio, among others. If you use Spotify or TIDAL, Connect mode allows you to control playback directly from their official apps, sending it directly to your device.
Chromecast Audio support opens the door to playing YouTube Music, TV audio, radio, podcasts, and local content from any Chromecast-compatible app to one or more destinations simultaneously. For those who require more local libraries, there's DLNA support for streaming from network servers.
Voice control and remote control
You can ask Alexa, Google Assistant or Siri to play music, turn the volume up/down, or skip tracks from your phone, smart speakers, and HomePod. If you prefer physical control, the Wii Remote enhances the experience by allowing voice searches and actions with Alexa without the need for a separate Echo.
The remote lets you pause/resume, adjust volume, mute and launch your presets with a button. Its pairing is very simple from WiiM Home and is compatible with WiiM Mini, WiiM Pro and WiiM Pro Plus.
Sound quality: DAC, ADC and gapless playback
The WiiM Pro Plus stands out for its DAC AKM 4493SEQ cutting-edge, capable of handling up to 768 kHz/32-bit and DSD512, with a wide dynamic range (SNR 120 dB A‑wt) and extremely low distortion (THD+N -110 dB at 1 kHz). For those who value detailed analog output, this is a substantial improvement over basic solutions.
Gapless playback is taken care of with a system of two decoders that remove extra samples at the beginning and end of each track, so the playback time is identical to the source. This applies to both compatible services and music stored on your mobile phone or local network.
On the line input, the Pro Plus uses the TI PCM1861 ADC (32-bit/192kHz) with an SNR of 110 dB. This component allows you to faithfully digitize analog sources for redistribution over the network or listening to them in other rooms without any noticeable loss of quality.
Equalization and sound adjustments
To fine-tune the audio, you have a 10-band graphic equalizer and 26 presets covering music genres, bass/treble adjustments, cinema, gaming, loudness, and voice enhancement. If you want a custom curve for your room, you can create it right from the app.
The manufacturer frequently adds OTA updates that incorporate advanced features; the ecosystem is in constant evolution, with Roon Ready certification, app improvements, and an announced parametric equalizer that will complement the fine-tuning options.
Supported inputs, outputs, and formats
On the physical plane, you will find analog line output stereo, coaxial digital output and SPDIF optical output. For inputs, there are analog line and optical input digital, allowing you to easily integrate players, turntables with preamps, televisions or consoles.
Playback supports music input and output up to 192 kHz/24 bits, with bit-perfect output where appropriate (the output matches the source format). Codecs and containers support MP3, AAC, ALAC, APE, FLAC, WAV, WMA, and OGG, covering most personal collections.
In protocols, in addition to AirPlay 2, Chromecast Audio, DLNA, Spotify Connect, TIDAL Connect and Amazon Music Casting, the system integrates with speakers and assistant hubs for hands-free routines and control. The Pro Plus's Bluetooth 5.1 is two-way, so you can transmit to Bluetooth headphones/speakers or receive from your phone.
Button panel, accessories and construction
At the top there is capacitive touch controls Play/Pause, Volume Up/Down, and a Preset are useful when you don't have your phone handy. The unit is powered via USB-C, simplifying setup and supporting standard power supplies.
Included in the box is a usb power adapter, USB-C cable, RCA to RCA stereo cable, digital optical cable, and user guide. The chassis is compact (140 x 140 x 42 mm) and weighs around 400 g, so it fits well in small furniture or stacked with other components.
Measured performance and key figures
For reference, the manufacturer declares SNR of 120 dB on the analog output and a THD+N of 0,005% at said output. The specifications are complemented by decoding up to 192 kHz/24-bit and the possibility of bit-perfect output, ensuring that the digital stream will respect the source format when appropriate.
Network connectivity includes dual-band Wi-Fi and Ethernet 100M, plus Bluetooth 5.1. On a practical level, this translates to stability for high-resolution streaming, especially if you opt for a network cable when Wi-Fi coverage isn't ideal.
Android compatibility, Apple Music, and quality considerations
If you use Android as a media center, the WiiM fits like a glove thanks to Chromecast Audio, Spotify/TIDAL Connect, and the WiiM Home app. However, Apple Music does not offer native Connect on Wii U., and its Android app uses Chromecast, which may limit quality compared to local playback or AirPlay 2 from iOS.
In the specific case of Apple Music with Android: sending by Chromecast may involve reduced quality depending on the app and content; Bluetooth also cuts out (the Wii U Pro Plus doesn't advertise aptX HD). If you're looking for true lossless from Apple Music, the most consistent route is to use AirPlay 2 from an iOS device or Mac to the WiiM; there is no native AirPlay from Android.
Alternatives if you are concerned about quality: use Qobuz or TIDAL with Connect to maintain high-resolution streams on the WiiM, play local ALAC/FLAC files via DLNA or from the WiiM Home app itself, or use a dedicated iOS device when you want to get the most out of Apple Music with AirPlay 2 on your network.
Multiroom experience and practical uses
With several WiiMs (or mixing with HomePod, Echo or speakers with Google Home) you can set up a flexible multiroom systemThe Pro Plus supports multi-room audio even when the source is input via Bluetooth or its physical inputs, opening the door to "linking" audio from a TV or turntable to other rooms.
Control from WiiM Home is intuitive: create groups by room, change playback queues and adjust individual or set volumesIf you also use the voice command, it's even more convenient for pausing, skipping, and presetting stations or playlists.
Limitations and details to keep in mind
It is worth remembering that the device is a AirPlay 2 receiver, not a transmitter: It cannot send audio to other devices via AirPlay 2. It also does not retransmit audio coming in via Aux to AirPlay 2, Echo, or Google Home devices, a significant limitation if you were planning to use it as a universal “bridge.”
In Bluetooth, although it is 5.1 and bi-directional, there is no mention of codecs like aptX HD or LDAC, so if your priority is the highest wireless quality, it’s worth prioritizing Wi-Fi streaming, digital outputs, or using an external DAC if you prefer.

Compatibility and variant notes
The Wii U ecosystem is Roon Ready and receives frequent OTA updates that improve features and stability. Some listings detail variants and features such as Item number 00106395, black color, and the use of Cinch/RCA and optical (Optisch) connectors in inputs/outputs, in addition to the presence of digital output via Cinch.
If you're coming from a WiiU Pro, upgrading to Pro Plus makes sense when you take advantage of its analog output to an integrated amplifier or amp, or when digitizing analog sources through its higher-level ADC. If you use only digital outputs to an external DAC, the advantage is reduced, although the clock/source/PCB improvements remain.
WiiM Pro Plus is shaping up to be a streamer with an excellent price/performance ratio: better sound, easier setup and lower total system cost by eliminating external DACs or hardware changes that aren't always necessary. For Android, it offers virtually everything, with the exception of Apple Music, where the best experience is achieved through AirPlay 2 from iOS or Mac.
