There is an IR x10 command console that can control up to 16 x10 devices for $29.9. A 3 pin appliance plug-in module capable of supporting 400 watts for TV and audio devices is 18.99. A 3 pin wall receptacle with a 20a rating is $56.

My primary concern (for these type devices) was the potential impact it would have on my old parasound 1200 amp and velodyne sub. Currently I leave the 1050 on standby and leave my parasound and velodyne on all of the time. Introducing the x10 or any other system would seem to bypass the standard power startup protection circuits I believe both the parasound and velodyne have. As a secondary concern, I don't know if the x10 system via it powerline commands introduces noise into a system connected to it.
