Adwiegart,
I use the Alan Maher Ref. II to best effect with the Powercell 10 SE. It works better ahead of the Precision AC, which comes with the 10 SE, rather than plugged into the 10 SE's outlets.
The Alan Maher Infinitys or CBFs, (Circuit Breaker Filters) are very good at clarifying the sound, when used in the breaker box. There are lots of fields in a breaker box because the wires must be unparalleled in order to route the hot wires through the individual breakers. I suspect this is whythese tow products are less effective on powercords and other paralelled AC wires.
I use a PE V Pro plugged into a transformer, which is plugged into the wall.
I find it best to not plug AC enhancers or other PLCs into the Powercell 10 SE. It's qualities seem to be best achieved by having the 10 SE as the last devise before the component, especially source components.
And thanks to tbg for the advise on getting the Speaker Cells next.
