I have always said if I had an incredible amount of money, I’d pour a lot of it into higher end stereo equipment. But us more secluded aspirational audio guys are a rare lot...
The problem comparing cars vs audio, in my opinion, is that cars offer more bang for the buck when it comes to an ostentatious display of wealth. And that, if I may be so bold as to say, is what drives (pun intended) high ticket auto sales. You can have the finest audio system in the land, and never be able to have a “look at me” moment out in public.
Just an observation.
