Yes that would be the case, as trigger normally takes away the entire power supply, so the same as operating the rear panel On Off switch. But triggers are normally initiated by the preamp so that power amps, sources (and in my case the amps in my hybrid speakers) are turned off or on when triggered to do so by the preamp.But Trigger in kills the whole M66, including the BluOS section, so you can't trigger in M66 from CD player, and at the same time start it via BluOS streaming. The whole M66 is gone from BluOS if you connect trigger in.
