Hi to you all. Well, I'm a bit of a newbie so please go easy on me. I have a Sony DAV 500s which I'm pretty happy with, except for when I play CDs on it. For watching films it seem fine to me, but with CDs in stereo, it sounds thin and lacks detail in the middle and treble. So I'm wondering if upgrading the two front speakers would make much difference. What do you reckon to this?
