Not having decades to work on building an endgame system I thought I would go for one from the start so I could just enjoy the music. There may be small changes here and there but for the most part this is it. Happy so far. I built the room while the speakers were being built. Professionally designed by Jeff at HDacoustics there is no drywall inside the room and this room definitely punches above its weight.
I think it's incredible what you've done with a nearly square room and relatively low ceiling. The level of attention that you've put into building out that space must pay tremendous dividends. Congrats!
