Ghostinthemachine, I can't comment on your experience since I'm not connected with Zu or their distributors, but if you haven't already bought alternative speakers do contact Sean at Zu and see what he can do. I believe they have run 60 day risk free home trials for many of their speakers in the past, and maybe this could be arranged for the Def4s.
It's a shame, since you're missing out on one of the most holistic experiences in music reproduction, which I am buying further into myself personally by purchasing the Def4s. Ironically enough, since you're not considering, I complete the transaction today.
