Could be excellent but disappointing

This radio is superb in it's design and function, easy and straightforward to set up and use and the display is brilliant, but I can only award 4 stars as the sound quality does not come anywhere near matching it's functions. Out of the box it's dull and muffly sounding with a little too much bass, the equaliser has only +/- 3db, setting to -3 bass and +3 treble improves it but it does not reproduce the crisp quality I expected from a radio in this price bracket which is a great shame and has left me feeling a little disappointed
