Every luxury brand is like that. Do you really think a Lexus is massively more expensive to produce than a Toyota? Brand engineering is not a scam. It is a key element of product positioning, like it or not, and the concept of "perceived value" has always been at the core of many pricing discussions in market economy.Of course you are right, but that's not how it plays out in the real world where the superficial does matter.
The difference between buying a Hermes Birkin bag or buying a 10k speaker cable is that the latter will sell the benefits with pseudoscience lies. Hermes doesn't - people just want one because of what it is, and the value proposition is just about feeling good. Some watch brands have tried that at times, pushing a movement that operates at 36k bpm as being more accurate than the typical 28k bpm. Which of course is stupid and dishonest (and I don't think they do it anymore).
And that's a huge difference, in my opinion. Try that is the supplement industry ("Our smart pills will improve your IQ") and the FDA will shut you down. I don't understand why some audio snake oil companies get away with it, but I guess it's simply because their customers don't sue over such claims.
