I will second rabbani about the crafft monitor,they built it for professional monitoring purpose,and their old hand made esotar tweeter are better than their new one,I guest they change it just because they can only built 1000 pair per year of those hand made one,contrary to their new industrial design which are not quantity limited,and funny to see also that others very famous speaker maker shift to other brand choice as soon as they ceased the old esotar production.
