I need your collective knowledge on the purchase for a DVD player. From the recommendations I will then start my research on which one to get. My budget is $500. I am looking to get a DVD changer, 5-7 disk capacity, progressive scan, DVD-audio or SACD preferable. Order of feature importance is as listed. Which ones would the forum recommend for video and audio performance. My display is the Princeton 32" monitor, and my audio system composed of Dennon 3300, all 5 magneplanar speaker and Velodyne HGS15 sub. Thanks in advance.
