Have to say, I have no complaints about sound quality. I use both FM and CD (CDR/CDRW with mp3s) regularly. I was listening to some commercial yesterday and thinking of this thread I was actually impressed at the quality as the sound of the person's voice was kind of wandering around the speakers. Seemed very clear and clean and roved well around the car.

I'm no audiophile though so to a more "highly attuned ear" I suppose it could be lacking. To me it sounds great.
