I have not compared those directly, but I have heard speakers from both companies. If you want a sound in the same family of Klipsch, then Zu is a good choice.
Von Schweikerts do have a different sound from Zu, a good deal less forward and they can be pretty laid back especially with certain paired components. It has taken some tweaking to get my Von Schweikerts as forward as I would like (which isn't as forward as Klipsches or Zu). Out of curiosity, which Von Schweikerts did you hear and how did you think they compared to the Klipsch sound?
