pianoloverus I don't see how #2 would be a problem acoustically since the lid opens out into the room.
My point with #2 is that it has the piano opening to the shortest distance. IOW the distance from the piano to the wall (bottom of the photo) is much shorter in this arrangement. If that door is open, that gives the sound somewhere to go but if not, the sound bumps into the wall much sooner than it would in placement number three.
And as you can see, placement #2 is very similar to the placement I had with my first piano, so I’m speaking from experience, from what I literally heard with my own ears. And the difference I heard when the piano was repositioned was amazing beyond words.
Oh and my piano is 5’8”, so also similar to @redrabbit ’s.
