The EQ varies wildly from track to track and I listen to a mix of genres and don’t tend to listen to albums as I find it feels like listening to the same song for 90 minutes so mines always on shuffle.
I was racking my brains, as I was sure I posted a response to something similar, then I found it and I realised it was you...
http://www.golfgtiforum.co.uk/index.php?topic=284674.msg2600731#msg2600731You playing different genres etc might be part of the problem, this isn't a Dynaudio specific problem. As I said then, Dynaudio is just the amp (software and physical) and the speakers making 400w of power output (versus the standard 80w), it won’t however impact the bitrate of a song/tune being played, which is the important part to everything, so if the song/tune is a low quality bitrate then it’ll sound inferior to a higher bitrate tune. The higher the bitrate, the better the sound. However, regardless if that tune is being streamed/played at a high bitrate or not, if the original digital file being streamed is of a low bitrate then it still won't sound as good, you normally find this with 80's/90's songs which have very compressed original bitrates. So in the car the Dynaudio simply allows the tune to sound at its best as it's being delivered with more power.
I do agree that the the system is sensitive to bitrate variables, I find this when I am listening to Amzon Music's predefined playlists or stations, but that's not the fault of the system, in-fact one could argue it shows the system has excellent response. IMO the front-stage sound from the Dynaudio tweeters is awesome for a factory system, so much clarity. They beat any of the BOSE or HK system I've had in other cars. The Subwoofer can be heard but not felt (which again is really nice). I like that the Dynaudio EQ is really expansive & flexible so you can adjust to cater for your taste in music, perfectly, wither that be electronic, vocal, or any type of genre where sound sensitive is needed. It's also the sort of system that allows you to turn it up loud without distortion.
Given you are listening to many different genres, I think you're probably going to struggle to find a perfect one-setting-fits-all EQ.
