I found the Dynaudio system a little bit disappointing at first; a bit bright sounding with a lack of low-end power. I have to say though that now, after a few months of ownership, it sounds really good and I often get asked if I have a sub in the car! It can really surprise you with some tracks. I guess it takes a while for the electronics to bed-in and the speakers loosen up - a bit like home hi-fi; I am surprised by how much it has transformed though. In my experience my iphone sounds 'thin' and brittle whereas CD gives by far the best sound.
