Review on 🔊 Up2stream Pro V3: WiFi & Bluetooth Audio Preamplifier Board with Airplay, Spotify, and Remote Control for DIY Speakers - Arylic by Tammy Freeman

This amplifier board is really worth buying. The 4Stream app works very well on iPhone and almost as well on Android. I bought this mainly for airplay support and it works fine. The sound quality is amazing but you have to give it very clean power. Two complaints: I wish it had a filter for noise current, and I wish the IR receiver was wired and not soldered to the board. If you mount it in a case you will need to desolder and lengthen the IC so it can be placed somewhere else. I also wish they had sold a separate volume potentiometer.
