I think Gazza is right on order, though I am aware that some spend hours on cable-dressing and I don’t, and that these thing sometimes seem to have a big impact and sometimes not. You could raise the 300PS up a rung if that helps Burndy dressing, but the diagram at least looks a good starting point.
In my stacks, I found the most important thing was keeping preamp PS away from preamp and (more important) phono stage.
You may get a PS for the NDX2 at some stage - it makes a big difference. You’ll want that on the brawn rack too.
Finally, if your LP12 has a Lingo, I’d suggest you keep it away from 552 or your phono stage. That means not putting it below the 552 and hoping it’s not audible, but it also means trying to avoid plugging the Lingo into the same socket (via power block or not) that has all the other boxes. IME, unless you have an actual buzz from bad cable-dressing or box placement, they will matter less than not messing things up with your LP12 PS.
