There are so many variables at play in different systems, not least the person and the room. And yet, without generalizations no one would have an opinion and there would be no fun discussions or debates. That doesn't mean there are no valid points made about the gear or technology involved, but they're typically overstated and underdetermined. At least that's what I've perceived.
On the other hand, one very real (and fairly transferable) fact about listening to CD's vs. streaming for me (I do both) is the the different framework for the experience. One selects and puts a CD on, then sits and listens for a couple songs, if not the whole thing. This is different than most of my streaming, which jumps from song to song. Often, too, I wind up seeing a text notification or some other distraction. This is my fault, but there it is a way of listening much more vulnerable to fragmentation than CD's. (Or vinyl.)
I'm not getting rid of streaming, but I grew up listening to sides of albums, and the iTunes one-song-at-a-time thing was initially repulsive to me. Now, it's mostly how I listen, and I'm questioning whether that is something I want to scale back upon.
