I seem to recall you saying something about having zone 2 in use for something else. Does your Creek have a signal pass-through option? (I remember seeing some headphone amps that allowed this back when I was considering getting one a couple years ago.) If so, you could use the zone 2 output (and its remote volume control) to feed the Creek and still route the audio from the Creek on to whatever other device is using the zone 2 signal.
