Charles,
That Paris studio was Mega Studio, the A room. The bigs there are all TAD components (tweeters, horns, and drivers) put together in a custom config by Thierry Rogen, the studio owner.
The Mega room sounds pretty good. I do however prefer the bigs and acoustics in our A room at Capitol Paris, which are Genelec 1025s with ATC superdomes, Dynaudio tweeters, 15" TAD drivers and 18" TAD subs. Those, along with the 1036 mains in Plus XXX's Studio 1, also in Paris, are the best bigs I've heard. Both rooms were designed by Christian Malcurt, which may have something to do with it.
Sorry if this comes off as an ad.
