I use X10 to turn my two older Adcom amps on and off, and have been very happy with it. I got an X-10 IR receiver ($27.00), along with two appliance modules ($13.00 each), from Smarthome.com. I use my Home Theatre Master MX-500 remote to turn them on or off. It makes it really easy for the wife and kids, because I programed it into my "On" and "Off" macros on my remote.
