Zu speakers are very dynamic and detailed speakers, but this comes at a price of being quite sibilant, lean, and harsh sounding. If you like the Devore O96, I seriously doubt you would like Zu speakers. You must hear them first. Someone above mentioned AN-Js which would be terrific and would be reasonably priced if you can find them used.
I have not heard the Tekton Perfect SET, but the other Tekton speakers I have heard would suggest that they are contenders.
