You can stream high rez (or regular) files from your computer to your stereo with this combo with your Android phone or tablet (remember those?). Chromecast Audio cost $35 (often on sale for $25) and the ad free version of the app is $1.99. It works perfectly and is stable as hell, unlike what I used to use, BUbbleUPnP. It won't do 24/192 like BUPnP, but neither will Chromecast Audio for now. For that you need a regular Chromecast or Chromecast Ultra and a separate HDMI DAC, or one of my Kromecasters (only $3,499).
