Davey,
Were your old Shahinians speakers omni-directional? If I recall correctly, those speakers did not have tweeters that were pointed directly at the listener, but pointed the tweeters off-axis to provide a more diffused type of sound. If that is correct, it is possible that you simply have a preference for a more diffused, less direct, type of sound. I believe the Zu speakers have a super-tweeter that is pointed directly forward, toward the listener, correct? If you play material that is already "hot" on the high-frequency end of the spectrum, it could just sound harsh to you on the Zu speakers relative to the Shahinian speakers you remember.
As Eric said, speaker placement and room treatment may help tame the harsh high-end if you choose to go that route.
