For many reasons.

The most important one being that with age, my various experiences in both speakers and amps in my home, the listenings I had at dealers and shows, the articles I read from highly respected reviewers and the talks I had with designers, and other audiophiles, all those tend to the idea that for my ears, the best approach in audio is to amplify very easy speakers ( not necessarily very high eff ones ) with very few watts amplifiers.
My experience showed me that little amps are more musical than big ones. Once again, TO MY EARS.

In this philosophy, tough Wilson loads like the Alexia's have no place.

DeVore, Verity Audio, Avant Garde, Harbeth, some ProAcs, Tannoy, and many others are in the game.

I respect the tough load / big amps approach.
Musically speaking, those systems can sound awesome too. But the idea of itjust does not make sense to me.
Like having a Ferrari with an amount of breaking always active and needing huge power to overcome it, or having a Ferrari and attach to it a caravan.
