CD/DVD Players as Transports
I read a lot of reviews of A/V gear and in most CD/DVD player reviews the reviewers talk a lot about sound quality differences via analog outputs but I've never seen a good discussion of differences in players used simply as transports feeding an A/V receiver. I understand with DVD players there will be differences in picture quality between different players but I don't have a good grasp of differences in sound quality when a player is used simply as a transport. As a concrete example, I currently have an Oppo DV-980H DVD player that I use as I guess what you would call a digital transport (connected to my Integra DTC-9.8 via HDMI) and have read reviews of the new Oppo DV-983H and am wondering if I would get any sonic benefit upgrading this player (I realize the picture quality would improve but to be honest I'm not sure I would notice a huge difference in my set-up, same could probably be said of the audio as well!). To achieve better sound is it that I need to find better DAC's than the Integra and connect it using analog cables (though I've read the Integra's analog section isn't that great) or is there also variations among players used as a transport?
