Best speaker in the US $ 30-45.000,00 range

I would add the new Magico Q3.

What happened? Does this mean Tidal is no longer the unequivocal choice?

Two that have not been mentioned are

Zu's new speaker called "Dominance."

A doubled set of Coincident Pure Reference Extreme

Although I've not lived with them, the Wilson Sashas bowl me over in terms of their sonic attributes, have little in the way of peers in terms of fit and finish (I'll leave out aesthetics, being so subjective, though I really am crazy for them in that area as well), and (surprisingly) beat most of the midline reference speakers on price. My experience is they are also more inclusive of their partnering amplification than previous Wilson offerings.

If I was going to spend more than $15K on a pair of speakers, I've not heard anything that has impressed me as much as the Sashas. And, this is coming from a guy who was not much of a WATT/Puppy fan.

I concur with Trelja - the Sashas are a good choice if you like precise sound - an exception in the Wilson line, which is normally colored by a house sound that leans towards heavier resonant bass (especially in the WP line). Frankly, the others would not make my shortlist but my taste (in the minority) is not towards laid back mids and an emphasis on bass.
