I agree with Jeffloistarca and some others here. His breakdown is well balanced. Better speakers are also more revealing, so if you get great speakers and have cheap electronics, the great speakers will sound like crap, because they do a great job of reproducing the less than great sound of your electronics.
I am always reading speaker reviews in Audioreview where the consumer reviewer will say some speakers like B&W Nautilus sound like crap. Then they say they are not worth the money because you will have to spend alot on electronics to make them sound good. What they do not realize is, the crap they hear is the rest of their system, not the speakers.
