Yeah I still have a little issue with them dropping the "Smart Player" because even for most movie, video people these days do almost everything via streaming. I guess you can pull from other sources over the network if you want to get into all of that, but especially being its a 4k player you would assume that today it's rare to sell 35 dollar 4k discs to everybody and have to use the transport?
Seems a mistake removing the smart apps in my opinion directly on the machine. Not to mention if you want to process thru the oppo without an optical disc you are forced to essentially run another HDMI to the input if you have a unit to pull up the APP.
Ha, but I guess even video guys might have an old playstation hanging around they can run their Amazon or Netflix on! But it would be nice if the 203 internally processed it. Oh well.
As for stereo outs I believe all Oppo really ever did was simply jump another parallel set of RCA jacks out of the back and name them "Stereo" to make you feel better. It was always tapped off the 8 channel DAC for the last decade I assume. I don't believe they ran entirely separate 2 channel DAC boards so it always derived from the FL and FR on the chip.
Beyond that from my personal experience I was never that impressed with any of Oppos sound in stock form. Especially the overpriced Balanced BDP 105. I think the BDP 103 for the money was at least as good with most High res systems in single ended 2 channel anyway.
But both excel with a good custom Linear Power supply of course.
