Congrats on a great system Rob.
I was just wondering what you think about the advantages and disadvantages of having no sidewalls? Have you ever compared systems in a dedicated room versus a room like yours? I ask because my system is also in a space similar to yours with no sidewalls (in the living room for me) which opens up to other rooms to the side.
Did your audio designer comment on this and how it would effect it?
I'm a bit worried that I will never get to hear my system's full potential after spending loads of money on equipment. I see you are very content and I'm happy to see that it is not in a room that is not a fully dedicated room. It gives me hope!
I had listened to Rockport Aquila's (my speakers now) in a dedicated room at the distributor, but with way better electronics/sources than mine currently, and it was amazing. My system now is maybe 60-70% of that. Everything was better in the dedicated room, i.e soundstage height, width, especially depth, and dynamics, imaging, etc etc all the usual parameters.
