I was thinking I could also buy a Xantech AC1 ($70), plug a power strip into that, plug all my sources into that, and plug the DC power driver to the ZPR68. This would not be perfect, since the sources would all turn off when the last zone was shutdown. If someone was listening to a CD and someone was watching a DVD, if the CD zone is shut off 8 hours before the DVD zone, the CD player will sit there playing for 8 hours. Since it is generally unlikely I will be using different sources in different zones, this may not be so bad for a quick and dirty solution (if it would work).
