Sony XA9000es/Sony DVP-NS999ES

Hi -- I'm looking to buy a new/used/NOS CD/SACD player and have been looking at both of these units. The price differential is quite substantial -- around a thousand dollars for demos/used pieces.

For the record, I recently added a 555es CD changer to my second system and, just to state where I'm out, it is behaving very well indeed with over $15k of speakers and electronics; I have no real complaints at all.

Anyway, there are good buys out there on the two units I mention. I'm just wondering if there are any "real" -- significant -- differences between the two? The XA does seem to be utterly bomb-proof.

PS, I do not need video playback, so I would just ignore that in the cheaper unit.
