@dayglow Your comment made me realize that yes, the majority of my coverage was from the lower level floors in larger rooms. I did also visit every floor and listened in dozens of rooms. There were some notable rooms there, like the Constellation/Magico setup, AXISS room with the Air Tight monoblocks and New Franco Serblin speakers, and a few others. Bayz audio also sounded better than it did before.
Every chance I get, I try to listen on Sonus Faber because I typically don’t like them and I try to make myself understand them. Whether it be at shows, other dealers, or other customers. I associate the way I feel about them similarly to how I feel about MBL, though I have historically found MBL to be more pleasing of the two. This year was no exception, but I can say that was the best I ever heard the Sonus Faber Aida sound. I’ve typically only heard them with the McIntosh 1.2KW amps or other similar gear. The whole Boulder and DCS stack configuration enabled the Aida to be more dynamic and open, while seeming quite natural. That said, it was still not holographic to me. It did not give me a sense of performers playing in the space, despite the system’s resolution and wonderful tone. I guess I personally place a lot of value in a system’s ability to deliver the goods holographically.
Regarding the Wynn, Vimberg and Karan, I think any mechanical nature of the sound you perceived was likely due to the size of the room. It was enormous for the size of yhr Tonka D, especially compared to something like the massive Estelon in the floor below them. I do think different amps can absolutely shape the final delivery of speakers. I demonstrate this for my customers all the time. What I did love about the sound in the Wynn room is that it had the speed and imaging of something like the Borresen (perhaps not as pronounced), with the heft and fleshed out natural delivery of the Lansche and Thrax combination I heard in the Florida Expo. The Wynn audio was definitely quite effortless in my opinion, but not relaxed and not the most refined. Still, it moved me the most compared to any other room in the show.
