An audiophile dilemma

A friend of mine just bought the JBL PRX635 stage speakers and they sound just great!
These are not the typical high end speakers that are in demand among audiophiles and they cost far less than their high end siblings.
Sometimes I wonder if all the money is well spent, because for far less $$ someone can become an owner of a pair of these JBL's and be happy for the rest of his life.
Are those high end (and very expensive) speakers really better than the JBL's?
