HD radio is just a lossy compression scheme to allow digital audio on the analog AM and FM broadcast bands. You'll get the same or, more likely, better fidelity from the same stations' streaming.
Streaming HD radio on Aurender
I have been enjoying HD radio on my Bluesound Node2, especially since here in Philly we have Temple radio station WRTI,using Tunein. However now using an Aurender I can only use Shoutcast and I can't find it. Does anyone have advice? Do I have to find other stations? Thanks, Joe
