I took a CD to check out how the stereo sounded in the 330i. I was impressed with the quality of it. It sounded excellent, it got very loud but never distorted. I didn't play with any of the EQ settings or DSP modes, I'm not even sure which one it was on. Likely the default because this was like the first day it was out at the dealer.
Although after realizing that its a $1200 option I am hard pressed to suggest it to 325 buyers. I'm pretty sure that as great as it is you could do as well if not better in the aftermarket with that much money. But since its standard on the 330 I would be more than happy with this system in my car
