Congratulations and nice pictures. One thing you may want to do is also try the QS8s using 5.1. In my room with back walls to reflect off of a back speaker (not QS8s) didn’t sound as good to me with matrixed recording like DD-EX or DTS-ES Matrix. Only DTS-ES Discrete 6.1 sounded better than the two QS8s did working alone. While that could also have something to do with how my Denon handles the Matrixed recordings. So in my case I found more speakers doesn’t always sound better others have found the complete opposite just something you might want to consider.
