Arylic Up2stream Amp V4 WiFi Bluetooth Stereo Amplifier - Multiroom

In this review the Arylic Up2stream Amp V4 is evaluated as a DIY-friendly network amplifier for homeowners and hobbyists who want to add wifi and Bluetooth streaming to existing speakers. The bottom line: it is best for people who want a compact, networked amplifier board that supports multiroom playback and high-resolution files without reconfiguring a full AV rack. The unit's ease of setup via the 4STREAM app and its flexible mono/stereo modes make it a practical choice for bookshelf, ceiling, or desktop speaker projects.

Key Features

• Wireless multiroom: Add the Amp V4 to several zones and use the free 4STREAM app to play the same or different audio on each device for flexible multiroom control.
• High-resolution playback: Supports lossless formats including FLAC, APE and WAV so you can stream higher-quality files than basic Bluetooth alone.
• Wide streaming support: Compatible with Spotify Connect, AirPlay, DLNA and UPnP plus many services like TuneIn and TIDAL for numerous listening options.
• 50W x 2 output: Delivers 50 watts per channel into 4 ohm speakers, making it suitable for bookshelf or tower speakers and many home audio projects.
• Flexible inputs: Accepts local sources such as USB sticks, NAS and line inputs alongside network streaming for blended setups.
• Web and app control: Configure playback, EQ, multiroom and firmware updates through the 4STREAM app or directly via a browser using the unit IP.

Who It's For

The Amp V4 is ideal for DIYers and homeowners who already own passive speakers and want to add modern streaming capability without replacing speakers or amplifiers. Installers building whole-house audio or a small multiroom system will value the multiroom control and the ability to group units on a single network.

It is less suitable for users who need an integrated packaged AVR with HDMI switching or those who require extremely high power for large outdoor PA rigs. Also, users who prefer a purely physical remote interface may find the app-forward design limiting.

Pros & Cons

Pros

• Compact board that converts passive speakers to networked streaming with stable Wi-Fi and Bluetooth connectivity.
• Supports lossless formats and many streaming services for better sound quality and source flexibility.
• Switchable mono/stereo modes and the ability to pair two mono units for higher combined power offer adaptable installations.
• Speaker protection and an advanced circuit design make it safe for bookshelf and in-wall speaker use.

Cons

• App and web control are required for many features, so users who want only physical controls may miss a dedicated remote.
• Not a drop-in replacement for AV receivers that need HDMI or extensive surround processing.
