Loki, I am streaming TIDAL Hi-Fi from my iPhone via a digital dock. The dock sends the raw digital bitstream to my Marantz SR6003 AVR via optical cable. The Marantz's DAC then decodes the digital bits to analog. I have to say, this setup sounds amazing. CD quality. I have played tracks that I have on CD and compared. The TIDAL tracks sounded at least as good, if not better for whatever reason, possibly due to my CD player not having a digital out so it is only outputting analog to the Marantz.
