Review on 🔊 Arylic Up2stream S50 Pro+ - WiFi & Bluetooth 5.0 Audio Receiver with aptX HD, ESS Sabre DAC AKM ADC, Multiroom/Multizone, Wireless WiFi Audio Receiver with Airplay, Spotify, and Internet Radio by Shane Tomko

I love using it with Spotify Connect. The only thing is that it's a bit weird connecting it to Wi-Fi, it doesn't until it does. But the cool thing is, you don't have to use Bluetooth - use the Spotify Connect app instead. The included app has bass and treble controls, which is nice if clunky. The main disadvantage is that you can't get a direct level into your amp. It's always an adjustable volume from your phone, which I don't want. I just want to control the volume with the amp and nothing else so I know my amp is getting the best possible signal.
