This is a very non-tech stab at your question -

The ICBM operates off of a 12v "wall wart" transformer, converting AC to low-voltage DC. I'm not sure that AC power issues would even appply. I have mine powered off of an inexpensive powerstrip, plugged into an always-on receptacle. It's perfectly quiet and clean.

I tried to auto-on the ICBM by plugging it into a switched outlet on my pre-amp, but that resulted in a "speaker pop" when turned on and off. Both Outlaw and the knowledgable folks here advised me that the ICBM is designed to be an always-on device that draws minimal current thru it's transformer.

Hope this helps.
