Oh don't worry i suffer from a bit of OCD too, all the resistor colour codes have to be orientated the same way so you can read them from left to right, it has to match the orientation of the labeling on the PCB, all components have to sit flush. The attached pic says it all really, all the "DALE" marking and resistance codes had to be the same, and i had to ensure they were all perfectly centered between the two PCB's. That's after resistance matching them between left and right channels of course..its fun being me.
