OK. FWIW: When I listen to music, then I listen to music and when I watch TV, I watch TV. And yes. I did build a 4ch decoder in the 1970’s to be able to listen to “Atom Heart Mother” and having Alan walk diaginally through the room for his Psychedelic Breakfast was indeed nice, even if the matrix 4ch had only 3dB separation…
My requirements are quite humble: To have rear speakers and possibly a subwoofer in the future.
