The Adcom doesn't appear to have a trigger, so it sounds like you flip it on and the power amps come on 10 seconds later. But the pre-amp goes into standby immediately and waits to be told to turn on. The pre-amp doesn't really start powering up and stabilizing until you pick up its remote and turn it on (or hit its front panel power button). I guess you are still distributing device start-up so they all don't come on at once, but I'd think you'd get the system more stabilized if the only device being switched by the Adcom was the amp - turn on your pre-amp (bringing it from standby to on), then kick on the Adcom so the amp fires up. I don't know - I may be overlooking something, as it's late and my eyes are a bit blurry...
