Christian,
I did both routes. The upgrade is definitely an improvement, it has been 2 years since I listended to mine, so my memory of the exact improvements is a little foggy. If memory serves me, I noticed the improvements in a more refined presentation with improved dynamics and low-level detail.
I since have upgraded to the Essence and couldn't be happier. The improvements in the level of bass depth over the Druid is immediately noticable. Overall it is a great speaker, and I enjoy it very much, especially considering the price point.
The Druids have a little more "punch" than the Essence, but both are very musical and enjoyable. If you really enjoy the Druids, the upgrade is a nice and easy improvement to be had. If you want something a little different, but still want the Zu sound, Essence all the way.
