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?
As someone on the “inside” of this industry with intimate knowledge of how systems from each manufacturer stack up against each other…. Lincoln Revel, Lexus Mark Levinson, Volvo/BMW B&W, Cadillac AKG.
