My personal issue with any of the digital audio broadcast formats so far is that the broadcasters chose quantity over quality. More channels can be crammed in, trading that for lower fidelity. Audiophiles in Europe hate DAB. Here HD radio is typically implemented with secondary channels and lower fidelity (lower bitrate) on the main channel. Sirius XM is the extreme example. I can barely listen to the music channels for more than about 10 minutes. I would probably abandon FM radio if we went down this path. I might not be typical, but I would be gone.
