From Vandersteen 2CE to Devore Gibbons 8 or Focal

I presently own Vandersteen 2ce speakers and I am less than pleased with the treble response in my room (too bright). I am thinking of buying (used) either a pair of Devore Gibbons 8 or Focal 836V speakers. I will have to travel quite a distance to hear either pair of speakers, so my question is in your opinion, which speaker would be a step up for me? I am looking for a smooth sounding treble which I don't get now. I listen kind of nearfield, about 7' from the speakers. Associated equipment is Classe 15 amp, Modulus 3A tube preamp and Raysonic 168 tube cd player.

Anyonw?
