Hi, I think the other ones you can consider are the horns Fp15 or fp10. They are from the same company as the universum though different sounding. However, they are very similar to the AN E in terms of looks and placement, and I think much better than the AN E. I have heard them with various SET amps at a friend's place. I think those who like AN E will like them and these are better. Joel of 6 moons also has a review on them if you want to do further reading
Have not been impressed with any of the hORNs speakers except the Universum, which is very good. However, I haven't heard these monitors...I would be inclined to go with JBL studio monitors though if going down that road.
