Need, well maybe not but despite that it could be fun if you tell us a little about your impressions.

Any speakers that you thought were really good and or interesting?
For context: I am biased, I love (and listen to every day) large speakers, preferably with a compression driver and fairly large bass drivers. In other words, I love the absence of compression, low distortion, good directivity control (I prefer slightly more direct sound than reflected sound), and the absence of obvious coloration. I also prefer accurate, well-controlled bass. On the other hand,
I am quite loyal to the setups at the exhibition — if something sounds good, I forgive the flaws and just have fun, as I understand how difficult it is to achieve excellent sound at an exhibition in a random room. But if any of the above “doesn't work,” I go to another room.
With that in mind, I hardly even enter rooms with small speakers, as I don't expect to hear anything there that will please me. Even cool speakers such as D&D, Kii seven, medium-sized Genelecs (who know how to be “much bigger than their size”) don't really impress me. They're cool, but not my cup of tea. Ok, at this exhibition new D&D sounded much better than Kii seven, both had a bit too much bass (this often applies to problems that are fixed on the second or third day of the exhibition, when demonstrators adjust the setup to the room, but I heard what I heard.) But the D&D sounded more accurate and balanced, while the Kii's bass got out of control.
Let's move on to the category of large floor-standing speakers. In short. Estelon with Kondo amplification sounded the most balanced in my opinion, this is the kind of sound you would expect from high-end speakers. I liked how the B&W Nautilus sounded this time. I had heard them before in less successful installations, but here the sound was excellent. The Rockports sounded great with Electrocompanit, I almost always like Rockports. The Kharma sounded a bit harsh and not very pleasant, although I remember being impressed by how they sounded in Munich. The Magico sounded a bit sharp this time and didn't impress me much. I almost always like how Vivid Audio sounds.
There were other examples of good-sounding systems, which is generally what million-dollar systems demonstrate. To say that I fell in love with any of them — no, hardly. I'll prefer the JBL 4367 or Everest, which were not there this time

By the way, about the new high-end JBLs — sounded good, but I got the impression that they had taken a step away from 4367, difficult to describe, somewhat brighter in the middle and “rubbery” at the bottom — I wasn't too impressed.
Overall, most of these systems sound great in my opinion, although I find that almost all of them lack a little “liveliness” to make me fall in love with them. (Or the rooms were too big for them in many cases, compression drivers and large woofers could do their job better in these cases)).
Speaking of rooms...
Or maybe you can say which room had good acoustics for good hifi? It seems from your pictures that there were quite different types of rooms in terms of size, shape and so on at that hifi fair.
This time, there were many rooms measuring over 100 square meters at the exhibition. And this is something you won't hear at home when the speakers are working in a large room, far from the walls. Good speakers in such conditions create the effect of being at a live concert, which is difficult or impossible to achieve in a small room. And that's another reason to go to the exhibition — it's a worthwhile show, to listen to music in such conditions. At least I enjoy it.
