"I wish things cost less,(I'm talking new stuff from retail vendors here), but the best really does cost more, most of the time."
The best might be over 10x the price of something that is very good. The best might only be slightly better. Many are only concerned about what they will consider the best within a certain price range. For example, they might have a $100 to $300 target price range for a portable player, but would only consider spend around $300 if they consider it so much better than the $100 one. Production cost though might be very much related to economies of scale. So higher priced items might have to be priced so much higher, since when they are made in small numbers, just the design costs divided
by the small number of units will be very high. In addition the unit cost for the components will be so much higher when bought in small quantities.
How many will pay 10 times the price for something they perceive as being 20% better? Many would pay 20% more for something they perceive as 50% better, or perhaps even just 20% better.
Even if something is much better, it might be used in such a way that the higher quality sound doesn't matter much. For example, a music player to be used while exercising. For that use, durability, and low cost might be the most important factors. So if it is damaged or broken, it won't matter nearly as much.
