Review of Arylic S50 Pro+ wireless stereo pre

The Arylic S50 Pro+ is an audio streamer with a built-in preamp. It can be connected to various wireless networks such as WiFi and Bluetooth (with aptX HD audio support), and wired connections namely analog RCA Line In/Out, Digital Optical In/Out, Coaxial Out, Subwoofer Out, RJ45 LAN port, and a USB host port. To use the S50 Pro+, simply connect the output cable to the power amplifier ​​and a stereo speaker system. It allows you to stream music from streaming services like Spotify, Tidal, or Qobuz in high definition through the 4STREAM app or other compatible apps. It's also possible to add multiple S50 Pro+ to your home audio system for support for multiple rooms and/or zones.

We can open the device after loosening 4 screws and find out the various electronic components inside the pre-amplifier with a PCBA named "Up2Stream Pro DIY". We can find 6 main chips on the boardm namely:

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.

Notes:

Plug an Ethernet cable into the RJ45 Ethernet jack and the device will show up automatically in the app in about 10 seconds (Note: the mobile phone and the device must be on the same network).

A USB drive with audio files will also be automatically detected in the mobile app.

The 4STREAM app consists of 3 key parts:

For the purpose of this test, we choose to play music from the TIDAL Hi-Fi wireless streaming app. So we just find the amplifier (Power Amplifier) together with the speaker or use a speaker that has a built-in amplifier (Active Speaker) to connect with the Arylic S50 Pro+ wireless pre-amplifier, so we can listen to music.

We connect the Arylic S50 Pro+'s LINE OUT left/right with an RCA cable to the CD INPUT connector of the DENON PMA-520 integrated stereo amplifier, then connect the speaker cable to the B&W DM500 series speaker.

The song chosen for the test was Your Man by Josh Turner from the Best Of album in the Tidal app. 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 and the DENON PMA-520 integrated stereo amplifier 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 to complete song to use as an example. You can also find the original song on YouTube.

KEF LS50 Wireless II with Tidal Sound Test:

The song chosen for this test was Billie Jean by Michael Jackson, and part of the Thriller album in the Tidal app. Billie Jean's song stands out for its fun rhythm and low bass that makes us want to dance.

The Arylic S50 Pro+ is an entry-level wireless Hi-Fi audio system with a built-in DAC and preamplifier that handles high-mid-low frequency bands with sound quality that is worthwhile at an affordable price. The device can be purchased for $219 on Arylic store. Thanks to Rakoit for sending us the Arylic S50 Pro+ for today's audio test.
