Klipsch Heritage vs Zu audio

I have a Zu Def mk 4, and i am interested in the Klipsch Heritage line( probably Klipschorn). But there is no dealers in my area. I was wondering if any Audiogon member, went from klipsch to Zu or vice versa, and what were the difference you percieved in imaging and midrange etc...any regrets, and how about long term, any listening fatigue ?

do those two type of design deliver similar pros and cons ?

thanks
