For that price, a serious listening demo would be in order.
Audition each pair. Ask if anyone on here owns a pair of those. Bring cheese, or some food, and ask what they like to drink,...
scotch, or just some rc cola.
I have bought speakers unheard before, some have been blah,...and some have been amazing!
Dynaudio would be a unheard buy, but when getting into that much coin, I would want a definite answer to the highs of each speaker!
I am very finicky when it comes to highs that make me nervous feeling, or grit my teeth, or feel anxious.
Good luck on your search.
