Arylic A50+ review – An entry-level wireless stereo amplifier

The Arylic A50+ is a stereo audio streamer with a built-in power amplifier and support for wireless networks such as WiFi and Bluetooth as well as wired connections such as Ethernet, Analog RCA Line In, optical S/PDIF input, Subwoofer Out, and USB host port. All you need to do is connect the Arylic A50+ amplifier to passive speakers, and you can then easily stream music from streaming services such as Spotify, Tidal, or Qobuz in high-definition audio with the company’s 4STREAM app or another compatible app. Multiple A50+ wireless amplifiers can also be connected through your house to enable multiple rooms and/or zones support.

Getting started with the 4STREAM app

Download the 4STREAM application from the App Store for iOS devices and the Google Play Store for Android devices. The application supports English, Spanish, French, German, Italian, Portuguese, Korean, traditional Chinese, simplified Chinese, and Japanese.

The application consists of three main items with Browse, Device, and Settings. Let’s have a look at all three.

4STREAM device wifi

Device – Used to connect a new device

Let’s use WiFi as an example. We’ll need to follow four steps:

  1. Power on the device and connect your mobile device to your local network.
  2. Go to your mobile device’s WLAN settings, and connect your phone to SoundSystem_ xxxx SSID (Short press the Reset button if the hotspot is not found)
  3. Open the 4STREAM application, and follow the instructions in the application.
  4. Select a 2.4GHz Wi-Fi network (only 2.4GHz networks will appear), enter the router password, and wait for device initialization

  • If you have multiple A50+, or other Arylic devices connected to the same router, the router password is now saved.
  • Some Android phones may ask you to allow the use of the SoundSystem WiFi network. Please select “Yes”. If “No” is selected, you will not be able to set up the system successfully.


4STREAM A50+ and S50 Pro+ devices

Our A50+ amplifier now shows up in the app together with the S50 Pro+ wireless pre-amplifier we have just reviewed. You can check other methods such as Bluetooth and Ethernet in our earlier review.


Arylic A50+ Settings List

Let’s go through the six options from the Settings section.


4STREAM rename device

We can change the name of the device to something more meaningful

Speaker Info

app A50+ Speaker info

It displays the information of the connected device such as the IP address, the MAC address, the SSID, and more.

Alarm Clock

4STREAM Alarm Clock

We can set the time to start the device automatically, for example, to play music in the morning to wake us up.

Preset Content

4STREAM app presets

We can define up to 10 presents for our preferred playlists in the app. The first six can be accessed with the preset keys from the remote control as well.

Sleep Timer

Arylic A50+ Settings

This is used to enable an automatic shutdown after a period of time defined by the user, and up to 90 minutes.


EQ Equalizer

Equalizer function to adjust Treble and Bass values.


That’s where you will be playing music from online streaming services such as iHeartRadio, Spotify, Tidal, Qobuz, and Deezer all of which may require account registration.

Audio test with the Arylic A50+ wireless stereo amplifier

Test requirements

For the purpose of this test, we choose to play music from the TIDAL Hi-Fi wireless streaming app. The connection is easier than with the pre-amplifier, since an amplifier is integrated and we can just find a pair of passive speakers to connect to the Arylic A50+ and listen to music.

We’ll need the following

  1. 4STREAM app
  2. TIDAL Hi-Fi streaming app
  3. Arylic A50+ wireless stereo amplifier
  4. B&W DM500 series speakers by Bowers and Wilkins


KEF Connect Spotify TIDAL 4STREAM


Wiring could not get any simpler, as we just had to connect the left/right speaker cables from the B&W DM500 series speakers to the Arylic A50+ speaker terminal.

Connecting to the TIDAL app

TIDAL with A50+ and S50 Pro+

Country music test

The song chosen for the test was Your Man by Josh Turner from the album Best Of streaming from the Tidal app.

TIDAL app Arylic A50+ "your man"

The song “Your Man” is particularly striking with the unique vocals of Josh Turner, especially the deep bass. The volume is constant, and the atmosphere of listening to music is comfortable and enjoyable.

We did not adjust the equalizer, treble, and bass in the 4STREAM app in order to listen to the unmodified sound from the original song.

Note: The audio tested through the Tidal app is copyright protected. The reviewer has no intention of infringing on the copyright of the song in any way. Therefore, only short videos were recorded up to 2 minutes long, and not the complete song to use as an example.

YouTube video player

You can listen to the Arylic A50+ compared to the Arylic S50 Pro+ from our review “Arylic S50 Pro+ Wireless Stereo Preamplifier Review“.

Pop-dance and R&B audio test

The song chosen for this test was Billie Jean by Michael Jackson, and part of the Thriller album on the Tidal app.

TIDAL billie jean

Billie Jean’s song stands out for its unique rhythm, fun drum beats, and low bass. If you watch the music video, you’ll see the artist’s dance moves following the rhythm smoothly with the music until the end of the song.

YouTube video player


The Arylic A50+ is perfect for listening to music in small rooms with an area not more than 4 x 4 meters, or larger rooms with the Arylic A50+ and several sets of speakers covering the whole area. That would be using the Multiroom/Multizone feature and combining the Arylic A50+ with wall-mounted or in-ceiling speakers so can play music in various rooms/areas in the house, so we can enjoy listening to music wherever we move. That is truly a music paradise.

The Arylic A50+ is an entry-level Hi-Fi audio system whose main highlights include support for modern wireless music streaming, and a built-in digital power amplifier that delivers music at an affordable price. The wireless stereo amplifier is sold for $199 on the website. We’d like to thank Rakoit for sending Arylic A50+ Wireless Stereo Amplifier, and the S50 Pro+ pre-amplifier for review.
