I'm not sure whether you meant "no comparison" as hyperbole, Gandme, but according to Sony the mass of the XA9000ES is 35 pounds, 5 ounces, whereas the mass of the DVP-S9000ES is 27 pounds, 12 ounces, more than 6 pounds less. But the mass of the XA5400ES is only 22 pounds, 8 ounces, so you might conclude that it is the inferior unit. I have never heard a XA9000ES, but a number of reviewers claim the sonics of the XA5400ES are superior to those of the XA9000ES. Go figure.
