I also hear the Sopra's at AZPONA this year but they were in a huge room without their own 'space' and definitely wasn't the best I've heard them. The Focal rep was apologetic that they weren't set up properly and also should be mated with the better Naim amps. He also share his opinion that the Sopra 2 was a significant step up from the Katana (for what that's worth). I also heard the Golden Ear for just a few minutes but to me and my brother it wasn't doing anything special so we moved on. (I wouldn't consider our brief experience with the GE any kind of review or opinion). I'm not a big fan of subs or powered speakers but that's just me.
In general, I find the Sopra 2 very easy to live with - easy to drive, easy to place and are very musical regardless of the genre. It's always inviting, involving and thrilling. While no speaker does everything well, the Sopra 2 does a lot right. If your able to get a good deal on a pair I doubt you'd feel any buyers remorse.
Good luck on your decision and happy listening!
