Review on 🔊 Arylic WiFi & Bluetooth 5.0 Home Audio Amplifier - Up2stream Amp V4: 50+50W 21V DC/2.0 Stereo Channel & Mono, Multizone Streaming Board with Airplay, Spotify Connect for DIY Speakers by Jeff Hall

For a DIY board this is a great device. It's capable of producing a lot of good sound. It has its own app that is pretty intuitive. It supports native multi-platform streaming, although - at least with AirPlay - it doesn't fully support multi-point streaming, or at least has issues. IOW, if you're streaming to this board from iTunes, you might not be able to stream to something else at the same time. I have a strange issue with the WiFi on this board which is interfering with some other 2.4GHz WiFi devices. I am still troubleshooting and it has been a pleasure working with Arylic's tech support staff. They sent me a replacement unit to make sure the glitch wasn't a one off issue or something and overall was a big help. Wi-Fi, Ethernet and AirPlay/DLNA/etc. are handled by the Linkplay A31 plugin, so I'm now contacting Linkplay tech support for more answers.
