Unless I'm mistaken, Chromecast is limited to 24/96 resolution, whereas Qobuz goes up to 24/192, which matters to some people. Also, there are more expensive and sophisticated streamers on the market that many audiophiles prefer. To be able to use the Qobuz app with a hi-resolution UPnP/DLNA streamer/renderer/DAC would be a big plus for a lot of audiophiles--me included. ;-)
