A satisfied Magico S5 2024 user. The first pair in Colorado (November 2024). I provided more detail in my post on
@Amamoy2 thread discussing "
Diffusion for Front Wall," so no need to duplicate that here. However, I think the same considerations apply in your search.
Our room (a multi-purpose room not a dedicated listening room) has multiple hallways and a large stairwell joining it. Acoustically, it is a difficult room to deal with. The dimensions are roughly 21.5' wide x 28' long x 11.5' high. Somewhat similar dimensions to yours but, in all likelihood, your room is more challenging in terms of speaker positioning and orientation due to its L-shape.
In our room, I tried the speakers initially on the 28' long dimension as the front wall and then the 21.5' dimension as the front wall. In this room the 21.5' front wall proved superior.
Every room has its own unique sonic signature. I learned that I had no alternative but to work with the room,
being particularly mindful of the room's bass response, and choose the speaker location (and therefore the listening position) carefully. For me optimising the bass response of the speakers in the room was the first step, and foundational prerequisite, to obtain what I seek in overall sound quality.
Advice is worth what you pay for it and this is free. The room is the first component in your system. All of the speakers you are considering are capable of delivering satisfying sound quality. However, if not set up properly in your room, all are capable of disappointing your expectations as well.
I don't know where you are located but, unless you are expert in setting up your system by yourself, the dealer you purchase from might be a major consideration in which speaker you choose. Not only for their expertise in speaker setup but, potentially, for an in home audition.
