Now't wrong with a bit of healthy obsession

Thin cable is fine and dandy if you were lighting a bulb or charging your iPhone with a bit of AC but this cable has more to do than that.

On the other end of it is a hefty inductive load, it may have tuned itself a bit to reduce the peak but sooner or later it is going to want to reverse the current in a coil winding PDQ. It will try to control that current using a chopper circuit which depends on measuring the current flowing some way away. Did you fit the optional braking resistors?

Fat, low resistance cable takes the strain off more expensive components.
