    Good luck with that......I have been trying to explain this to Kevin for a long time. You may be more articulate than I, but I am not sure you are going anywhere.

The stand alone unit takes a 50A, 250V twist lock balanced plug. If EVERYTHING in the audio system plugs into the same power unit, I have a hard time seeing why a wall mount unit would be better than the same version of a standalone unit and the wall mount unit may actually be worse.

    With a standalone unit all audio equipment plugs directly into the back of the power unit. Therefore, the only external influence is your power cords.

    Whereas with a wall mount unit, the audio equipment plugs into a number of branch circuit receptacles that are in-turn wired back to the wall mount unit. So with the wall mount unit, you introduce more variables with wiring from the wall mount unit to your receptacles as well as the receptacles themselves. Also, EMI, RFI, and compatibility influence the wiring over these distances.

    I can see where a wall mount unit can be useful when you need receptacles in various locations, particularly when you can place a receptacle at a remote media server in another room (so you can ensure that your remotely located devices share the same power, neutral, and ground as the audio devices in your listening room)(otherwise you are introducing different grounds and neutrals into your audio system through the interconnections to these devices.)
    I wonder if you and Mike are just getting the terms mixed up between "stand alone" and "wall mount." I suspect Mike is referring to the 15 to 20 amp 'table top units" when he references the term "standalone" versus the big 60 to 100 amp "wall mount" units. Its about amp rating not the descriptive term. Of course I could be completely wrong.....

    when I made my 'can't compare' claim, I was referring to 20amp 110-120v plug in boxes compared to 'big-boy' 70amp 220v 5kVa and up hard wired panels.

    50A 250V twist lock connected boxes are equivalent to the large hard wired panels in concept. likely there might be some differences in performance, but I'd be guessing about what they would be. possibly the 400 pound Equi=tech 10WQ with the Nema Steel 12 cabinet might have build advantages over a stand alone box......or not.

    if you plug your power cords into the stand alone box, it also means the transformer is in the room in proximity to your gear.....a mixed blessing.
