Different than cars, but not too different.
B&W, Benz, Audi, huh?
I prefer Range Rover.
Why these brands?
Why not Toyota, Honda, Nissan, or Hyundai ? They they great safe cars that dry very well. And Toyota/Lexus, Honda/Acura, and Nissan/Infinity are more reliable and safe than BMW, Benz, Audi, Range Rover, etc.
For me in audio, if I could only choose 3 WELL-KNOWN brands under $25K, they would be Revel, KEF, and B&W.
But then again, why Revel, KEF, B&W when you could get much less expensive speakers like Ascend, Philharmonic, NHT that may sound equivocally just as good?
Just like in cars, there are many factors, not just SQ, which in itself is purely subjective.
Let's face it. People drive BMW, Benz, Audi, Rover, Porsche, etc, not only for their drivability, but also their aesthetic, prestige, and pride of ownership. Some people feel the same about audio as well as anything else in life.
