Congratulations.
I think the comment: "The goal of all these manufacturers is to create a speaker that disappears and makes you believe, with your eyes closed, that the musicians are in the room with you." Is a great one. Definitely one of the goals of high end speakers. It is a trick that requires all your components to work together to achieve.
Different designers still end up with very different sounding speakers. The soundstage, image size, and focus on details (kind of the volume control on details vs the primary instruments). The weight of different female vocalists. You would think all high end speakers would converge... but they don't as much as you would think.
Just a word on disappearance. One of the traits of my Sonus Faber Amati is their ability to disappear. I loved these speakers from the moment I replaced my Sonus Faber Olympica 3 with them. After about a year just loving them. I realized, they really did not disappear. That got me interested... so I started working with their placement. I made a few big adjustments just to verify I was not way off (listening for a few days)... I quickly realized I was close, then small adjustments... particularly with toe in... the rule of thumb, cross the beams behind your head. Turns out in my room, straight forward... they were gone.
I guess another plug for taking ones time... over time dialing you speakers in.
