I've abandoned internet radio. I've discovered there are much better ways to access information and music on demand. I am very satisfied with Apple Music via iTunes to Airport Express connected to my Pre-Pro. iTunes Radio can quickly retrieve iHeartRadio, NPR and many other AM/FM broadcasts. Of course you can get the same experience from your Marantz Pre-Pro via Airplay. Now, while Airplay is convenient for casual listening entertainment, I also have one of my laptop's wired to my OPPO-205's usb DAC, which is connected to my Pre-Pro; and, I've got to tell ya, this connection to access Apple Music, as well as my iTunes Library, gets me a music entertainment experience rivaling stereo SACD quality. At any rate, your Marantz pretty much permits you to get media in all manner that it can be delivered so why not just experiment, maybe connect your PC or MAC to your Marantz via HDMI and/or usb and then try out Apple Music.
