Tube amps are normally chosen for a "romantic" high end i.e. smooth and melifluous. The Jolida hybrids also have that type of sound.
I am not sure if you will find a tube amp bright enough for your tastes. Have you considered a solid state amp? They usually sound a lot brighter in the treble.
Also condsider that the Dynaudio (esotar, esotec etc) tweeter if far sweeter and more mellow sounding than the equivalent Focal metal dome...so mating Dynaudio with a tube amp may give an overall sound that's too romantic for your tastes.
