My two cents from the very brief 'audition' where I stopped by:
1. I suspect if you love ML, the Neolith gives you WAAAY more scale and midrange weight than any CLX, or the other 2 smaller Hybrids i have heard, let alone bass...while still delivering that 'stat alacrity that ML lovers crave
2. This guy finally has WEIGHT and POWER to rival a big all-cone speaker. The CLX/Descent combination to my memory did not give me anywhere near the same impression of scale and depth...suspect its related to the bigger panels?
3. I felt that the room was a bit small for the Neoliths, and would have preferred to hear them in a bigger room with a taller ceiling to see what they can really do.
4. On drum kits, on the upper bass elements, I heard alacrity and detail now with weight and spaciousness from the PANEL. To my ears in the deeper bass, acknowledging that it sounds trite/contrived, but i felt it thickened more than i would have preferred and i wondered if it is was the old panels/cones integration thing. And specifically, the lower bass was more 'thickened' than i have heard from the XLFs and the Focal Grandes in the same room.
5. Ultimately, i preferred the coherence and sense of CONTROL of the delivery of full-scale sound from the XLFs and Focal Grandes within the same room...it seemed more in control to my memory. They and the Alexias seemed more easily able to cope with the room. While the scale of the Neolith was big and dynamic, the music seemed to 'shudder' a bit or 'strain' quite a bit in comparison with the 2 bigger speakers and to a less extent i heard pretty big scale from the Alexia and it never seemed fazed. While the upper elements were incredibly transparent at times so that i really felt there was 'no speaker' on these individual sounds/notes (the shaker rattle on Dead Can Dance was incredibly real), i still felt when the music really got going in scale, i felt the overall system 'strain' just a bit to reproduce and try to keep everything together. And that sense of reproduction of music came forward in my mental notes...something i did not find in listening to the XLF or Focal Grandes.
While they may/may not have had quite the upper range alacrity, the overall balance seemed better, along with the sense of effortlessness, which (on my own personal priority list) is more important to me when relaxing and listening to music. I have grown to appreciate alacrity, speed and detail but i have never ranked them as number one on my overall priority list. Effortlessness, propulsive bass, midrange magic and extension rank higher for me.
That said, those 2 of the 3 speakers are also 3x more expensive and the 3rd is much smaller (Alexia) and i did not seek to put the Alexia through the same paces as the guys did on the Neolith.
6. In the final analysis, I find the Neolith a killer speaker at its price, stat alacrity, huge scale, big bass, and as much as i like the Alexia for 15% less, it is tough for that 15% more in price to walk away from all that the Neolith delivers. For me, it would depend on the room as the Neoliths are huge and certainly on first impression seemed to need the room.
I do not think it delivers 'ultimate scale/unflappability', and i would like to dig deeper into that bass snap to see how much was room vs design of the speaker. But for that rare 'spooky presence' thing that MLs do nicely, there is a weight and scale i have not witnessed before myself in MLs which is truly impressive compared to its forebearers. And so again, if you love that and get the bass integration right, its hard not to love what ML have done...and again at a price that is incredibly competitive relative to the other comparable speakers i have heard in this room from time to time.
I suspect setup is very tricky and room size (ceilings) very important to get right. With the incredible attention to detail by KJ/Pedro, i could imagine many people living with these speakers for a very, very long time.
