Having used DAB for a while and been disappointed with the sound quality - even with BBC Radio 3's 192 Kbps, I purchased the T31 FM tuner, and got a three element FM aerial professionally installed, and I have to say I'm blown away. The sound, imaging and detail is superb, to all intents and purposes there is no stereo hiss (you get more hiss from the different audio sources that are used), and even compressed commercial stations come out with an enjoyable vibrancy.
To be honest the difference between FM and DAB is half way between FM and AM - thank goodness for FM - and my T31 has brought a whole lot of fantastic live and recorded music and plays to me.
