The device has some decent features for 35 bucks and allows you to stream from your DLNA music library, but it's not really an alternative to Chromecast or CCA:
- I don't think the device can be used to directly stream from music services such as Qobuz, Tidal, Spotify, Amazon Music, etc.
- Does it support bit-perfect streaming like the CCA?
- Does it support hi-res (i.e. 96/24) files without sample/bit rate conversion?
If you want to use a music streaming service with the device, I guess you can stream from your phone to the device via Bluetooth or Airplay, but there will likely be a degradation in the signal. The beauty of Chromecast is that the app you use to stream is merely a controller; once the stream is established, the streaming is (generally) performed directly from the source to the Chromecast (or CCA) device. There are exceptions with apps that cache the streams for gapless playback, but in general, Chromecast and CCA streams bypasses the "middleman", which can mean less degradation in the signal, or at the very least less dependency on the app being active in order to hear music.
