I to am looking for a Blu-ray for strictly 2 channel enjoyment.
I think the Oppo 105 is to new to have any reviews yet on it however, from what I have learned so far in general, as long as you are going to use an outboard DAC you probably will be fine keeping the Oppo 93. However if you are going to use the inboard DAC then I would suggest getting the Oppo 105 because it will have a better Stereo DAC than your Oppo 93.
The only issue I can foresee, and I honestly don't know enough about digital to give a definitive answer is, that I with the Oppo 93 to use an outboard DAC you must change the settings in the setup menu, some players must down mix the LPCM for stereo use and some players don't. If the Oppo 93 down mixes but the Oppo 105 does not then I would go for the Oppo 105. I am just not 100% sure about the stereo down mix, good or bad? Maybe someone else can clarify.
