I have that amp and like it very much, although it needs a relatively easy load to drive. I tried it on my hard to drive Sonus Faber Cremona's and it just could not drive them effectively. In your case, the Focal speakers seem like a relatively easy load. In addition, John Atkinson notes in his measurements
"The Focal Chorus 807V offers excellent measured performance, though its treble balance will require care in choosing source and amplification components if it is not to sound too revealing."

From those perspectives, the match may be good. I have not heard the Pathos with any Focal speakers, so cannot comment on the sound quality. The Pathos is a nice mixture of tube and solid state with a refined, laid back quality. Fine for jazz, female vocal, and such but not suitable for hard rock, but you probably already know that.
