I want to comment that I find the standard sound system in UK spec X3s to be acceptable. Of course much depends on what your aspirations are, possibly because I have a couple of very good hifi systems at home, the differences between the BMW systems aren't so important to me. I also tend not to like lots of high frequency unless quality is _really_ good as it can be tiring, all the glass in cars can do nothing other than cause pesky high frequency reflections. Hence the lack of tweeter for me is a good thing. With both my X3s I was disappointed with the standard sound system at first but once the speakers had about 10 hours use at a reasonable volume level I found they greatly improved. Initially I good vocals and bass but little in the way of guitars. The sound is fine now and decently balanced. I have a 128GB usb stick with 900 albums ripped as MP3 VBR V2. I have room for about another 800 albums.
