I went through the same decision few weeks back as well. I have Denon 4520, so I first bought DBT-3313UDCI to use denonlink. After two weeks of troubles, I returned the player and go with Oppa 103. Oppa just offer much more features, better remote and better gui than Denon does. When I had Denon, I had few random HDMI handshaking issue, especially with 3D blu ray disk.
If you only looking for SACD player only, than maybe DBT-3313UDCI is an option. But as bluray player (or plus media player), I would stick with Oppo.
