I did a fair bit of research into these QM.................went for top of the range Roberts for around �150.
It's stereo with a great sound.........most of the others are mono.......... with so many stations available, you need presets......................the Roberts only has 5..........could do with more.
If you're a geek, then the sound isn't quite as good as DAB, but it's fine for me. Leave your router on all the time and the radio is available instantly.
Anything in particular you need to know?
