I really wish I had not bought this option. It sounds so compressed compared to FM. There is a lack of bass, lack of clarity in treble and mid frequencies and a significant loss of dynamic range. I mainly listen to Classical Music on Radio. My ex also feels the same.
I can improve the sound on DAB to some extent with the Graphic Equaliser but then the FM sound gets screwed.
£300+ down the drain. I could have bought Variable Sports Steering (VSS) instead for £50 less. And to add insult to injury, DAB is free now just a couple of weeks after I got my car!
I am really very hacked off.
