I'm sure everyone would agree that it would be nice if Dune had a pass through mode. It doesn't, and it really upset when I found about it. That fact alone delayed my purchase for many months. But then I said, "so what" and bought the Dune anyway. There is banding at times, but when I compare it to playing the same video via my Blu-Ray player, I see banding in the same spot. But I've seen hundreds of perfect sunsets, underwater scenes, or whatever type of scene where you might expect to see a stepped gradient, and there has not been a trace of banding on almost all of them.
You mentioned getting an Oppo. One thing you may wish to try is buying the new Oppo and use it as a video processor. It has an HDMI input that would allow you to process the Dune output through it. That might eliminate the incompatibility between your Epson and your Dune, if there is such an incompatibility exists.
I don't think any of the players based on the same chip-sets offers a pass through mode, so I am pretty sure it is not a design decision made by the Dune engineers. Others who know more about the chip set may wish to comment of this, again.
I've never had an audio dropout, by the way. Maybe I'm just lucky, or maybe my gear is more forgiving of the Dune. Of course, now that I've said this ... I'll get lots of banding and no audio at all! Video is a crazy hobby.
