I agree with Peter. For that reason would I choose the Oppo.
However, if you are absolutely 100% positive that you won't care about SACD/DVDA, Denon makes VERY fine players. It also just looks very nice, and you would have a more unique player than what one would commonly see.
I don't have SACD/DVDA capability, atm. They both are very fine players, I'm sure. I suppose the first thing I would research is the FW support, historically speaking. Hm.
Meh, go with the Oppo.
