[Twitch Massacre]

Agree with Mr.SugarSkulls. I'm a producer and audio engineer as well and find the B&O to be a money trap. There's no real difference in sound quality that I could notice except that the B&O has slightly better bass output at high volumes than the standard system. BMW automatically trims the bass ass you drive the volume up on their systems to protect the speakers, seems this trimming is more subtle on the B&O but that's all I can see as an advantage. Aside from that they're both "ok" systems for a car at best. The B&O does look much better though.
