As someone who likes to dig for weak signals on occasion, my opinion cannot be repeated on a family-oriented board :.>> It's rather similar to In Band On Channel (IBOC) on MW, where the sidebands can potentially hide or mask a weaker signal that would otherwise be able to heard, if the signal was analog.
However, from a purely listening standpoint, if mother nature cooperates and you get a nice strong signal, the audio quality is, no doubt, better than a standard analog signal
