strengths and weaknesses

Never listened to the Focal Sopra 2’s... but I do own the SF Olympica 3’s. Best sounding speakers I have ever owned...they are plain superb across the board. Feed them the quality power and source they so deserve...and they will perform magic in your room. 

Focal sopra 2 has Much more intresting sound.  Sonus Faber is too silky and soft for my taste.

I have heard both and I think they are both very fine loudspeakers.

But I am not in the market for new speakers.  I assume you are though because you posed the question.

So the more important question is what do you think?  Which one sounded best to you?

Totally depends on what you listen to???

Heard them both. I liked the Olympica 3's much better. Seems better balanced.
