The Harman Kardon gives you an option in the iDrive to turn off surround, and you then have a "true" stereo system. I have no idea why it's on by default, because the fake surround is truly horrible, like a bad karaoke machine.
The main reason for me to get the HK is that it has better tweeters.
Otherwise, Harman Kardon is hardly audiophile - it's a branding mark more than anything.
