YOLO dude. I too have those feelings sometimes but honestly I cant find anything I don't like about my Axioms so I don't know what I would even look for. You cant miss what you don't know your missing. And yeah, real wood is the shit. I veneered all mine and I just sit and admire them sometimes, bad to do during a movie.
Well, I have never been happy with my Vp150. I have a older one, from 2004-5? And my QS8's were great for 5.1/7.1 but for Atmos they need to go.
My Subs are fine. So the only thing left is the fronts (M80's). If I'm going to do an entire swap, now is the time. As for room treatments, don't get me started. But yes, very very important.
