Doesn't have to be worse than AM, but it is
DAB could give excellent quality if a station is over 96kbps and using AAC HE v2 codec.
Unfortunately the main stations still use the bitrate-hogging MPEG 1 Layer II. And the rest are stations that all play the same narrow playlist at 32kbps AAC HE v2 and sound rubbish because of it.
Get rid of duplicate playlist stations, phase out MPEG 1 LII and there would be enough space for some decent sound quality.
