I enjoy following your posts on your Soundlab speakers and I have never heard them although I have talked with a couple of people with a lot of experience with them I would suggest that even though a show environment isn't the ideal venue for hearing systems or music it does offer a very concentrated opportunity to listen to state of the art systems that provide a very wide range of sound. You might come away from that still loving your system but it might also temper your assertions about how excellent your system sounds in comparison to other high end standards. I also think it is likely you have tailored your system to the genres of music you listen to. As far as I can tell that primarily means classical, choral, and a dose of jazz. One of the nice things about the shows is you do get exposed to a wider range of music although it is still true that most of what is played falls into fairly standard audiophile fare. This is everything I heard at the recent T.H.E. show in Costa Mesa. https://open.qobuz.com/playlist/32705565 Anyhow, you might decide to spend a day or two at the next audio show that it is convenient for you to travel to and try to maintain an open mind about what you hear.
My experience of show sound is that it rarely delivers. There are exceptions. I bought my speakers at T.H.E. Show in Costa Mesa 2023 after hearing them in the PranaFidelity room, which featured excellent sound. I was able to thoroughly evaluate them with all kinds of different music that I had brought with me on CD. I am still enormously happy with my purchase of the PranaFidelity Dhyana speakers. But that was one of just three or four rooms that I had heard there that had good or great sound. My experience at that same show one year later wasn't any better; just a few rooms with good or great sound, the rest mediocre or bad, regardless of how expensive the systems were.
A generally much better opportunity for exploring good sound has been for me hearing friends' systems at home. I have learned a lot from this, and can confidently say that I would never have arrived at the quality of sound that I did without that inspiration and challenge do do better with my own system.
The experience of hearing friends' systems for a long time mostly corresponded to what you say:
