Hello, Schism.
Your system is further along than mine (slowly working on it). I've got Paradigm Studio 20 v.3 monitors in my Home Theater system that (I'm guessing) may have a somewhat similar sound.
I'm curious about your thoughts on your various Zu cables. What led you to try them, and had you tried other brands before them? I've got Morrow Audio sp5 speaker cables that I really like.
Regards from another "ZERO" guy.
