Hey poges! We all have our compromises and preferences etc. For ME, I hate surrounds on stands. IMO, that layout doesn't present the source material as well as surrounds up higher/behind/ and aimed forward. Not saying that it's wrong for others, and sometimes that's the only thing that you can do in a room. Personally I think even though your wife is an absolute trouper, she's lucky in a way. My surrounds stick out from the wall almost 19". One is in a medium traffic area, and at nearly 30lbs, nobody hits it more than once. Lol! For your room, stands might be just what you need, but since you asked, my opinion is put them on the wall.
Also, since we're on the topic. I was meaning to ask for awhile now about your mains. In your pics (very generous btw) they look very far apart which is fine, but I'm wondering about imaging, and center image. For example, in stereo, is the vocalist in the center etc. I gotta dig up the rabbit hole thread...
