okay i'm afraid that as to the unit knowing where it is i just use the home power unit plugged into the rear of the empeg and just the two phono plugs into the back of empeg. The empeg fits into a ordinary cage but the cables have been removed from the rear. At the moment you just have to plug in the two cables and then slide in the unit. It could be altered to allow you to slide it in and use the plug at the back of the cage.
That way the empeg knows it is at home

all cables are hidden in the back leg and my father would be easily able to alter wood sizes and number of shelves etc.

As to price that would be about the same coss as a normal hi fi stand but he would be selling the so prices as over to him
