Dedicated stereo outs...Other than that its the back of a bdp-103...
The quality of stereo reproduction also depends on the quality of the power amp distributing it relative to the extra 2ch outs.
I think it is worth holding onto a bdp-103 or any decent BD player until Oppos next 'UHD-BD player' over this Cambridge by a mile imo.
Provided the streaming format hasn't completely overtaken UHD-BD by then.
Part of emerging UHD BD article, from WIRED:
"The bigger hurdle to 4K Blu-ray adoption, of course, is whether physical media carries any weight to begin with anymore. Unlike the first transition from DVD to Blu-ray, when digital downloads were still a nascent business and stacks of discs were the norm, this move comes at a time when the concept of owning a shiny movie-playing pancake feels as antiquated as carrying around a pocket calculator".
Surely the article isn't taking AV enthusiasts opinion into consideration, but the masses that bring in the main bulk of profit. Kids & the "who cares it looks & sounds good to my ears" brigade... Provided they can get access to the storage & bandwidth they would need to stream anything like the quality UHD-BD will provide.
Lets hope disc content comes ample & quickly in 2016. Although with all the studios behind it, newly released movies should be fairly rampant.
I really don't mean to seem so negative about UHD-BD Vs Streaming, but it feels like an age getting here.
Here's to the success of UHD-BD
Fingers crossed... on both hands!
