Hi, I also have the Focal Sopra 2, Focal Chorus surrounds and am waiting for the Focal Sopra Center to arrive this week. I am using Marantz 8801 as a preamp/pocessor and am extremely happy with it.
I have tried using the Oppo 95 as a preamp before buying the Marantz and the Focals, but the sound was horrible so I would definitely recommend using a real processor.
