Yeah I mostly see uncompressed PCM which my NAD processor calls ‘Direct’ and that’s mostly what I see these days. And I’m fine with that.
YouTube videos with music tend to be better in stereo as it mangles things when some of the signal flows through the center speaker at times. A lot of the music through YouTube is pretty darn good. That’s interesting Apple allows you to change formats but I’ve never drifted into Appleland. Unfortunately roon does not do that as far as I know. Or maybe it does in some of their DSP crap which I tend to stay away from.
