I used to own this receiver. It's pretty good, has a good, musical sound, but the x200 series was known for having an issue with digital audio dropouts, which many manufacturers had a problem with at the time. This is a problem for certain combinations of equipment with this receiver, because I had three different DVD players and two CD players connected to it at various times, and not all of them had the issue.
I never got a really 100% for certain reason as to why it happened. Basically, when flipping through DVD menus or the very first track of a CD, the first 1/4 second or so would be chopped off, presumably because the receiver had to "detect" the signal and figure out what it was. During playback is not an issue. Other than that, it was a great receiver. I really liked it, which is why I bought another Marantz to replace it when I upgraded.
If you have any specific questions about it, shoot me a PM.
