Point to point wiring VS. PCB drawing

Lower labor costs, manufacturing streamlining, and money savings. I'll go along with that, Ehider.

Point to point is preferable when used in a DIY set up, you can experiment with different wire to tune the sound to your liking. Damned hard to tweak a pre-made PCB...

While ground planes on PCB's are an advantage I have seen it misimplemented quite a few times on a professionally designed board. The advantage of point to point wiring is that everything can be grounded to one point and obviously it is very difficult to implement a shielded cable on a piece of copper clas fiberglass.
