A reply to the snarky monster cable comment...
There IS a difference between the Sony 5000ES and the 550 - even my dealer was skeptical about the quality difference. And I was of course reluctant to pay 2,000 dollars for a player. But before you laugh, go to your dealer and do a comparison. The 5000ES picture seems almost 3 dimensional vs. the picture on the 550 or other lower end models. So if you have a high end TV (my main TV is a Pioneer Elite PRO-FHD1) I would highly recommend Sony's 5000ES player for your blu-ray player.
