Your Golden Ears at 93dB are efficient enough you could use a Raven Blackhawk and have a greater sense of a dimensional envelopment probably than any of the others. https://www.ravenaudio.com/product/blackhawk-mk3/ A superb tube amp like that is key to the kind of wide and deep stage you want. After that, the next thing that will contribute to a sense of envelopment is super deep accurate bass from a Swarm or Distributed Bass Array. I'm talking real 3D envelopment not the gimmick Bose diffuse reflected sound effect. For that you don't need Bose you can put lots of speakers all over the place, or heck you can even wire your speakers out of phase it will sound like music coming from everywhere (and nowhere). You can tell I am no fan of Bose.
The kind of thing I am talking about will never sound like things are coming from behind you. Rather it gives the sense of being in the venue, no longer in your room but somewhere else. A feeling I find about a million times more involving. The extreme low bass of a Swarm does this without attracting attention to itself because it recreates the subtle low bass signature of a much larger space, fooling your brain into thinking you are somewhere else.
