I don’t have much experience in high-end luxury cars but I have owned a spectrum of brands from European,domestic and Japanese manufacturers.
Honestly I have never been impressed by a factory system. The H/K in our older Mercedes was a joke. We all know Bose is a gimmick. I’ve heard the Fender systems are pretty good but I’ve never had the chance to demo them.
The best I think I’ve heard is the Logic 7 in BMW.
What are some of your favorites?
I have never heard a factory car audio system that I liked or was impressed with. Which is surprising because I think it wouldn’t take a huge amount of money for the luxury segment to invest and attain good sound. I think they know the general market and that customer base does not typically look for better sound and thus the $ is spent in other parts of the car. It’s a shame.
