This whole “cost equals sound quality“ argument in hi-fi is very suspect. Here are a couple of reasons why.
A.) In many, if not all hi-fi components, the case equals more than half the cost of the component. Thus, you are paying for looks not for sound necessarily. I believe this is typified by the value proposition. Many have acknowledged for Schitt t audio products. Decent quality in a cheap case sold at a reasonable price. PS – I don’t own any of that particular companys products.
B) it is well known in marketing that price automatically equates with value in the minds of the majority of consumers.
C) the inability to totally characterize sound quality through measurement plays into the hands of the marketers in B.
and OK I will admit that there may be some boutique brands out there, using exceptionally high component quality who have developed intellectual properties that make their products worth extravagant prices. I don’t know. What I am saying, however, is that the opportunity exist for lots of deception through effective, marketing and appearance in shiny boxes and if there are not a lot of people taking advantage of that, then I guess we don’t live in a capitalist society.
