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
That is correct. The Adcom does have sort of trigger system, but it's an older implementation. There are two power cords from it..a thick three pronged one that goes directly into a wall outlet, and a thinner two prong one that can be plugged into a switched power outlet on the back of a preamp or receiver for example. If you plug that preamp or receiver into the unswitched outlet on the back of the Adcom, when that preamp is turned on by it's remote, it triggers the adcom line enhancer to turn on.
Kind of useless now because very few pre amps come with switched power outlets on the back any longer.
