I have a 2910 and have been happy with it, but upgrading entire system so mine is for sale in classifieds section. DVD video playback is superb, as is sound quality from DVD video. Standard CD sound quality is very good, DVDA is very good as is SACD. My DVDA/SACD collection is limited however as selection in Indy is not great. Easy to operate and set up, very solid universal player. My upgrade is leaning towards a Cary Cinema 6 pre/pro, Cinema 5 amp and Cinema 6 DVD player, although still shopping. The Denon is a great unit at it's price point. I don't have any experience with Marantz. hope this helps.
