I guess the strength of the Verity Leonore is it's efficiency. You would certainly want to use it with a tube amp. However, I do not understand the logic behind a rear-firing mid-range.
Looking at some of the music you listen to, do listen to Avalon. Avalon needs careful amplifier matching, but it can handle large and congested music. Plus, you need a modest-sized speaker with your room, and the footprint of the Indra or Eidelon Diamond would work. Big box speakers will not work in a room which is 13 feet across.
Don't worry about your room, and exotic equipment. I am sure you will find a speaker that satisfies.
