Is the marantz 30N or ruby almost a universal player


Hi,

The marantz ruby and newer 30n list as cd/sacd but their literature state that they will play dvd-rom high resolution files burned on a computer so does that mean it will play dvd-r blank disks I compile with 24-96 high resolution files.
Is there a practical difference between dvd-rom and dvd-a?

Why call it dvd-rom compatible rather than a universal player but for bluray?
