If you break any of those you still get benefits but not the full benefit.
And since this Oppo will be my next player, and I want it to last a few years I would like it to be able to detect and output all the latest codecs.
It is perfectly set up for this. I mean the timing of MQA is perfect. I don't think it was to late to implement into at least the higher end Oppo.
And to the person above that mentioned it is a larger file size. I believe if you compare apples to apples it is actually smaller. A 16/44 with MQA is smaller than a 16/44 flac. And I haven't read anything about it being noisier. And I have also been following it from the beginning. I could be wrong. I just hadn't seen that mentioned in anything I had read.
One of the beauties of MQA is the backward compatibility designed into it. I can take my current Oppo 103, point it at a file called song.mqa.flac that contains a 24/48 LPCM stream that has been MQA processed, the 103 will dutifully expand the FLAC data into a standard 24/48 LPCM stream and send that down the HDMI to a pre-amp.
If said pre-amp has MQA-capable DAC's, then the MQA code in the pre will decode (unfold) the MQA data into 24/192 and then the final rendering to analog will be also be adjusted to the 'fingerprint' of the DAC in the unit for optimum temporal accuracy.
So the player does NOT need to know anything about MQA to gain the sonic benefits.
But if the preamp is NOT MQA capable, it will just play the 24/48 LPCM stream and you get your audio, minus the high-res and the temporal adjustments. But still slightly better than the equivalent 16/44 CD version.
Oppo could license MQA for the 113 and implement the decode (unfolding) of MQA data into a selected resolution (say 24/96) and pass that high-res 24/96 LPCM down the HDMI to the legacy preamp or AVR. So that would be a reasonable level of MQA support in the base unit.
As I mentioned before, I'd expect the 115 to have MQA-Certified DACs as well, but also capable of doing what I just described in terms of sending decoded high-res LPCM to the AVR via HDMI or digital outs (which will a pretty common scenario).
