Just to clarify, I've set up several different zones (PCM native, PCM upsample, DSD upsample) all using the same DAC, a Chord QuteHD. I want to be able to switch between the zones using the iPad JRiver remote without having to remember to STOP instead of PAUSE playback -- if you only pause, the next zone won't play. At a minimum, a display that showed which zone was active would save a game of hide and seek to find the PAUSE'd zone. (alternatively, if JRiver were smart enough to see that the output path were the same, then switching zones might automatically shut down the zone of departure in favor of the zone of destination).
