Integra is Onkyo's high end brand. I wouldn't worry about CDs in DVD players-after all, it's a motor running the disc rotation (check), a little thing to move the laser (check), and a separate laser system for the CDs (check). If you're going to run the player to your reciever or processor with a digital coax or digital optical cable, you're not dealing with the player's DAC at all.
