Oppo Beta Group
That article doesn't specify which model Oppo model was used, but it would have had to be the 105 as the 103 and 203 do NOT have USB DAC inputs. The same method should work with the 205.I did some research and found this link. It shows how to connect an iPad to an Oppo 103 via USB or HDMI. There is a response at the very bottom that states it did not work on the 203 but with no details. Do you think it would be worth a try? I would lean toward the USB connection as I would think it should be more stable than HDMI.
I did some more research on connecting a computer to the Oppo and saw that there exist USB to HDMI adapters. Could I possibly use one of these from my laptop to the HDMI IN of the Oppo? Searches seem to indicate that Spotify can be connected to a TV via HDMI and the adapter does transmit audio.
There are also USB to RJ45 adapters, but I am guessing the Oppo is not designed to receive audio over the network?
For HDMI, it really doesn't matter if it comes from your iPhone, iPad, or your PC as long as you're sending a standard HDTV resolution (i.e.: 1080P).
