From personal experience I have found Totem and Nola speakers to be the most natural and musical while being the most forgiving of room dynamics. They have great speakers that are less than $5000 but also make them over $10000.
I currently am using Totem Twin Bisons and they totally disappear into the sound stage. Totem recommendations are to setup with the speakers firing straight a head for the best soundstage. Which I have validated. No getting anal about setting toe in, etc.
Just my experience which is worth nothing in the big picture
