Horns with good timbre and tonality?

I’m looking into buying a pair of horns for my next speaker. I sold my Sonus Faber Elipsa SE. Looking for a more realistic, more lively sound. I’ve heard the Triangle Magellan and enjoyed the sound, but wonder if there is better.

I appreciate speed and dynamics with good timbre and tonality. I know horns are good with speed and dynamics, but not sure if they can do timbre and tonality like SF can.

Looking at German Blumenhofer FS1 / FS2, French Triangle magellan, Fleetwood deville, Avantgarde.

It will be paired with Mastersound 845 Evolution SET or Auris Fortissimo amp.

Room size 40 x 15 x 8 feet

Must realistically play Solo Piano, Cello and full scale symphony.
