Why has focal raised their prices so much on Sopra line

I was looking at the Sopra 2 ,thinking about buying it ,it is a very good speaker it has not changed 
in 5 years thst I can see ,but the price has increased $4,000. Thst sounds like gouging to me ,
from $15 k to $19 k  if thatis thecase  the Wilson Sophia2 is a better speaker for the same price 
as well as night and day better resale value .
