Hey Aaron,
We have a 9000 installed with a Crestron CP2E and TPS 3100L in our Aquatics Center on campus. We've been very happy with it. The routing is pretty easy to work with. And with the Crestron control, I've given the Aquatics director a web interface so he can control the system, turn on zones, adjust volume, etc from his office instead of going next door to the room with the touch panel installed. They are very happy with it. Plus with the routing, it allows you to setup zones on your outputs.
