Ok so the audio path should be as short as possible however resistors lay in the way and well they are long. I get the film non inductive ones per recommendations and at a point to start working on a final layout. I have seen resistors standing tall in things I salvaged for parts however it seems the leads were treated w some paint or epoxy. Is this to compensate for lesser quality resistors where the leads can be inductive or magnetic or should I treat the leads the same way to minimize the audio path and not pick up unwanted sound?
