Hi chandybe,
The SoundLabs mentioned by Kalali are magnificent. I say that as a longtime owner and dealer. Currently I’m currently neither, but would consider it the highest compliment if someone said my speakers were "almost as good as the SoundLabs" rather than "better" than pretty much anything else.
Given that you are "hoping to find a line that clearly beats [very good] speakers in the ~10K range" and that "the listening space is quite large"...
You might consider straying from the beaten path and investigating small manufacturers who sell direct. Some of us little guys are pretty competent and bring a fair amount of innovation to the table. And without dealer markup, we usually offer pretty good value. Gedlee, Daedalus, and Volti come to mind. The downside is, more travel to get an audition.
Note that power handling is only one part of the equation when it comes to filling a large room. Efficiency also comes into play. What an 87 dB (that’s about average) speaker can do with 500 watts, a 97 dB speaker can do with 50 watts - but in the latter scenario, speaker and amp will be not be stressed. (This is a bit of an oversimplification but the trend described is correct).
"I just want my jaw to drop when listening to the speakers with any genre at all volume levels, if that’s possible :) "
Given a good recording and a good room and good system matching, and not being too literal about "ALL volume levels", imo that’s possible. (There will always be a volume level at which something becomes the limiting factor.)
