I absolutely love the system. I have bose headphones (both in ear and around ear ones) and I find I discover 'more' things in a song. Like background vocals or instruments being played in the song with the B&O system.
The thing is with these systems, its best to leave them default. (like mid bass, treble) etc as the B&O system should detect that. Thats what I have always been advised on these premium sound systems. Im not telling you how to suck eggs, but have you switched the 'surround system' on? Makes a difference. Also, if the base isn't punchy enough, then just turn it up.
I found it doesn't work on radio stations, well does but not as good as a CD. Also you'll find there is a huge difference in quality with the AMI (iPhone or alike) and a physical CD. I brought Examples album from iTunes and it doesn't sound as good as my girlfriends CD. (decided to compare them)
Regardless the format, other people notice it though. Usually commenting, 'since when did your car turn into a nightclub?!
I use to have bose in my A3, and this system is just much better. I believe the output is different on the systems.
