Regarding Zu speakers I greatly respect the opinions of several folks who post on Audiogon and happen to be Zu owners. I've heard various Zu speakers a total of 5 times and each encounter was disappointing (CES and RMAF venues). Perhaps they don't sound their best under show conditions (although I have heard numerous brands that manage to sound good at these shows). It may be the tendency to play them loud for demonstration. They just haven't sound very good so far in my experience.
