Is it possible for a high end manufacturer to overprice their goods?

@daveyf This discussion may as well branch out into economics, art, politics and philosophy. 

I mean some artist sold a banana taped to a wall for a $120k. Is it overpriced? No because it's art...

Yeah the adage "something is only worth what someone is willing to pay for it" is always 100% correct until you talk about utilities or medecine... Fortunately, we're talking about non-essential consumer goods here. So you could even argue that everything is under-priced and underrated considering labor costs. Only the high-end is priced 'correctly'. 

At the end of the day you vote with your wallet. The 'overpriced' question is not something for individuals to answer. It's more relevant if you're the seller. Ask the seller, not the buyer. 

Nope speakers are worth hundreds of thousands of dollars obviously! As well as amps, 20k + power and speaker cables etc. 

in luxury goods, price is one component of the value.  The manufacturer is not selling a function, they are selling the brand. Add limited production-  reduce the supply for the same demand and price may be increase even more.

The best part is: they don't need to sell any. They can keep selling the midrange stuff and claim trickle-down buzzwords and increase its price by 10%

Anything is possible 

No.  Fair market value is what a reasonable seller is willing to sell the product and what a reasonable buyer is willing to pay. If any product is sold, opinions from non-experts are worthless. I have some strong opinions about Hermes hand bags, but no one cares.
