Lovely set up, visually appealing and I’m sure the Focals sounds great!
I notice you have your subs angled in to your mains. In my experience when the subs are angled in to the mains the sound staging MAY be effected by the angle of the subs ( and yes, I am aware that below 100hz, bass is considered omni-directional.) I suggest you try aligning the subs in parallel with the mains (even if they are still set back from the mains) and listen while paying close attention for imaging shifts, you may wind up with a wider and fuller sound stage.
Great setup! It looks like we’re going down a similar path. I’ve got Aria 936s, Rel S5 SHO, and a Node 2i. Getting ready to audition a PrimaLuna Evo 400 and Naim streamer as soon as I get some room treatments up. I might steal your idea of putting diffusers in the windows of my new room. How do you like the SQ of the Node 2i in your setup?
The Vito acoustic panels, not so much, but they look damn cool! Some of my system is snake oil (the 6 dollar plastic rebar chair cable risers I bought at Ace Hardware) , but the visual presentation is as important to me as the sound.
Excellent room, must be a very enjoyable place to listen to some great tunes! Great job optimizing the listening without impinging on the livability factor. Cool use of lamps for acoustic and lighting needs - CB2 I think? I have to ask, can you hear a difference with the use/placement of the two types of diffusion panels?
