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

"Is is possible?" Sure it is! However, in a free and fair market the market will set the prices- not the seller. 

Said another way a thing is worth what someone will pay for it. 

There are some who seek the greater fool. Every now and then some bozo wins the lottery, gets an NFL contract, gets a lawsuit settlement, etc. Trying to sell to these types is a recipe for failure. There aren't enough fools with money to sustain a business over time who's building and selling overpriced items.

Interestingly if you sell to the classes you tend to eat with the masses but if you sell to the masses you eat with the classes.  

@yesiam_a_pirate You're missing something huge in your argument. Large manufacturers can scale production and outsource it to China in order to save a lot of money on production costs.

Smaller boutique manufacturers can't do that, unless they dropship or buy off-the-shelf modules and do minimal assembly. 

Success in the audio bizz seems to come from marketing, marketing, marketing... The quality of the goods and price seems almost secondary. Just produce something decent and hype it to the max. I'm astounded by the coverage around Schiit and now Gishelli Labs. Everything they release gets hyped up to infinity, as if they're "disrupting the market". They're not.  And these brands are relatively new. 

@kokakolia  I've had more problems with reliability from the mass market manufacturers then with the small boutique manufacturers. 

@czarivey : not sure what you just said has the slightest connection to anything I posted in my reply to you. Whatever "plan" you have drawn has absolutely zero meaning to me.
