Jim is right. The old rule of thumb was 50% on your speakers and divide up the remaining half amongst everything else. Then the pendulum swung to the "source is everything" perspective. Now it seems to be swinging back a bit and perhaps will settle in the middle. That being said, it is the easiest thing in the world to demonstrate that speakers have more impact on the sound than any other component in the signal chain. That doesn't mean you need to spend huge amounts on your speakers, only that you should choose them with care.
