I'm a Sopra No2 owner. The Sopra's are very sensitive to where they are placed in the room. If you get them dialed they will sound wonderful. The Sopra's will work very well when placed closer to the front wall than most speakers. This will give you room gain in the upper mid base and smooth out the presentation. In the Focal owners manual, it describes a very specific ratio of distance between the side and front walls. Start there and tweak as you see fit. As others have said above, the Sopra's don't need much toe in. They will still image like crazy unlike many other designs when not toed in. This will help keep them from sounding tipped up. Good luck and cheers.
Focal Sopra n1 - mids are a bit recessed compared to Lumina IIs
I upgraded my speakers from Sonus Faber Lumina II's to Focal Sopra N1. I am using the Luxman 595 class A amp, which I used for the Lumina IIs as well.
I love the bass and imaging of the Sopra N1s. Really good! However, one thing is bothering me. The mids or vocals seemed more recessed on the Sopra N1s when compared to my much cheaper Lumina IIs. Why is this? I miss the liveliness of the Lumina IIs from having those mids more forward.
Also, when I heard the Focal Sopra N1s at the store on a McIntosh 12000, I did not detect the mids being recessed. So it's very confusing also in that respect.
