vinnie2, you gotta remember that the output stage and the second 26 stage are 180 degrees out of phase when drawing from the supply whereas the input or first 26 stage and the output are in phase. Add the difference in signal levels and this why you want to decouple the input stage. The tail will wag the dog, so to speak.
Decoupling both input and driver stages generally increases the supply impedance of the driver stage and doesn't sound as good as just decoding the input stage.
