I've got to tell you all that the unit is shutting down after about 45 minutes of playing. I've troubleshot by switching from the ZP80, ZP100 (my other zone would always play) and the analog and digital coax outs and a cd player on digi out. (I did pick up a 'real' digi coax cable.) The unit sounds great but it's cutting off for some reason. '80 is not installed in the dock, it's riding sidesaddle. I spoke with a guy at Peachtree on Wed morning and he was helpful and concerned. I'm quite sure they're going to want me to flip it with a new one. I just want it to work as, like I said, it sound good for about 30-45 mins.
