Specifically, I just picked up an Adcom for my 2-channel setup. It does not have a 12v trigger or a 1/8 mini plug for auto turn-on. Basically, I have to physically turn it on and off. The unit is designed such that when power is absent the unit turns off so I cannot leave the power button in the on position and run it through my conditioner with delayed on/off timing. Do any of you leave with similar set-ups leave your amps on?
