Very nice system, Will. It's a shame that you are moving to another room. My previous room had tongue and groove wormwood paneling and looked quite a bit like yours. The room itself was 12.5 ft x 18 ft and had excellent acoustics.
In fact, a reviewer/columnist who evaluated my system knowing that I was about to move said, "good luck trying to find another room with these acoustics."
I notice that you have bare wood floors. If you were to, per chance, stay in this room, I'd recommend installing a thick pad and heavy berber-type carpeting to minimize floor reflections.
-IMO
