I move my Chromecast Audio from rig to rig(I know they are only $35.00) and it shines more when I stream digital via mini toslink to my Cambridge Audio 840C player/DAC. For the price of entry of $35.00, the built in DAC is acceptable when I just connect to my integrated amps via RCA analog. Only have Spotify and Pandora so I am sure with Tidal it will sound better also with the outboard DAC.
