From an acoustics standpoint, I would be tempted to suggest you change the orientation of your equipment and furniture.
I would place the display on the back, short wall and move the furniture to suit the viewing angle, further out in the open.
A good rule of thumb is about 2/3 back from the display. Sitting against a wall should be avoided.
I really like the kitchen area and I am also a big fan of salt and fresh water aquariums.
Keep up the good work and keep us posted on your progress.
