Wow, someone who listens to ATD: I have played ATD through many systems and found the dog in the back comes and goes(as does other intentionally out of phase easter eggs; the piano, the little girl/boy?, in the last cut the sports car now going from left to right behind you, etc), depending on speaker positioning. Try bringing them out ~ 3"- 6" at a time, and let me know when you nailed it.
Mad Scientist Audio's Graphene Contact Enhancer is a big deal, too
