I have also auditioned some some of the speakers you are considering. Sopra will Sound much better than Kanta in every way. They are really in different leagues. Given your budget, Sopra 3 is a better choice than 2. They are the same drives for tweeter and midrange, but the 3’s have more body in the lower octaves. B&W, in my opinion Sound a little thin until you get power running through them. Once the volume goes up, they will open up and sound really nice.
Dali and Dynaudio speakers will be a totally different sound than Focal or B&W. They are much more laid back. Given that your electronics are a little laid back, I would caution that you may swing to far in the other direction if you aren’t careful. Definitely audition them if you can, but I would spend significant time with them before making the purchase to ensure you will be happy 6 months later.
