Bill, my dealer spoke with James and he recommended either the RM15 or RM20 for my application, but I had the same problem with size constraints, so that's why I opted for the RM10. So I have everything but the 14B plugged into it, which is plugged into the wall socket, as per my dealers recommendation. He actually recommended this right from the beginning, even before I mentioned that I wanted a new conditioner.
I haven't tried the BP26 plugged to the wall as a comparison, so I cannot comment on this and I haven't tried plugging the 14B into the RM10 to see if can handle it. Worst that can happen is it throws the built-in breaker.
I used to have a Monster HTS3600 which I just sold, but before I sold it, I used it's amp meter readout to see how many amps everything was drawing, which would be the plasma, BP26/MPS2, Bluray and Rega and combined they were pulling 1.2 amps. Now according to the spec sheet for the plasma, it says it should have been pulling 3.0 amps alone, so I think amp draw is overrated for most things, so you may actually get away with the RM10 in your application.
