I stream to my Rotel set to Dolby PLIIx out to B&W speakers. It fills the room with sound- I dig it.
I know purists will stick with 2 channel. Two ch. is what I grew up on and I gave it a try and it just felt weak and thin.
Like I said- for me- the Dolby 5.1 is nice, lush and full. It's a more of an experience.
2 ch felt boring.
I also have a Pioneer Dolby surround headphone amp.
The same result.
I tried to listen to 2 channel through my Sennheiser 598's...
