I've had the Marantz dv 9500 for a week now. It's gotten a lot of use so I would say it's broken in. I have several sacd's and cd's of the same title that I've compared very carefully. I can't tell the difference, they sound identical!!! Excellent, but identical. I also have a half dozen dvd-a discs and they all sound inferior to the same title cd. All listening has been in stereo. I was going to sell my Sony cdp-707es, but now I'm thinking I should sell the Marantz. I believe the Marantz sounds as good as the Sony, but no better, and the Sony is 11 years old and works perfectly. The Sony also weighs around 40lbs and may outlast me. The only reason to keep the Marantz is the convenience of an all in one player, plus the ability to play surround sound sacd's which I will soon be able to play. Overall, I believe the Marantz is a fine product if you don't have a high quality cd player, but I am disappointed that sacd's sound no better than cd's, and dvd-a is inferior to both.
