I think I prefer three things in this order: warmth, upper midrange and details.
I think I have those from my current speakers - Evoke 20s so I would like add more presence, speed and disappearing speakers/imaging.
I’d like to stick with bookshelf, but you may be right. I have huge respect for Vienna Acoustics.
I will send you my list of 70 speaker brands, it helps me put things in context.
