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?
Fanatical and prejudicial Bose hater here.
You can say what you want about them, but in all fairness the tuning they do for Porsche is actually really good. The Burmeister option that costs five times a much only sounds marginally better than the Bose option.
Even factoring in the engine noise you’ll get on most models coming from behind you, they tune it pretty well for their cabins.
