Streamers, servers, players - woefully overpriced??

Look at the insides of these devices. They have very standard parts, power supply may be abit refined but still basic stuff.  All this for questionable SQ benefits.  We are still in the digital domain.  
Dacs and amps are considerably more complex and may justify some higher pricing.

why is streamer area so hyped and overpriced?  All to buy a pretty box?  And I do want improved SQ but it is tough to see it.
