You said "I have a further option about closing up the room since there is an entranceway to another room where the listening chair will be, and I will leave that open."
Interesting sentence since the phrase "…another room where the listening chair will be…" actually places the listening chair in the other room which would certainly justify leaving the entranceway open but which would also not give you the best results.
But my common sense occasionally prevails and that leads me to believe that the listening chair is going to be in the room with the equipment though close to the entranceway or perhaps even in the entranceway itself. The questions are how close to the entranceway and how wide is the entranceway? If you want free access to that adjoining space you would probably be better off not installing a wall there at all but simply having one larger room with the listening area at one end.
My gut feeling, and I really have no theory to guide me here so I may well guess wrong, is that the wider the entranceway the better and that the wider it is, the closer you will be also be able to sit to it. Overall, however, I think you would definitely be a lot better off if the entranceway were closed if you could manage it, or if there were no wall at all and simply the larger space as I suggested above.
The reason for that is that sound passing through the entranceway is going to be diffracted, ie as it emerges on the other side it's going to spread out in a widening fan-shaped front and this is going to happen for sound passing through the entranceway in both directions, including sound returning to the listening room from the adjoining space and most of that sound, assuming there are no noise sources in that adjoining room, is going to be sound from the listening room being reflected back into the listening room from the surfaces in the adjoining room. The effect will certainly add some diffusion to the sound in the listening room which is probably a plus but there's going to be a lot of strange directional sound patterns going on close to the entranceway and that may well make it a less than ideal location for a listening chair. Once again it's the unpredictability of the result that makes the issue problematic.
