Anyway, before offering any further commentary, i will seriously qualify myself.
I have planars so I am very sensitive to box emanations. These seem to be divided into three general types: Massive attack control of box colorations to give audiophile skeleton sound such as YG and Magico, box colorations that are sonorous and beautiful such as Sony, and the inbetweeners where there is some box coloration, but doesn't seem either aimed or unaimed to enhance the presentation. I would generally put Wilson and maybe Vincent in that category.
Shows must be hell on wheels for the manufacturers and representatives, because they encourage pontification and resolved judgement in contexts where that is not possible.
At home, in the familiar surroundings of my own system, I can convince myself that my hearing is a tame and malleable instrument. At the shows, though, it is more like a wild weasel on meth, an instrument but a rather unconrolled one that isn't tame.
If my hearing concentrates Asperger-like on a trait, I may not be able to get past that trait to get a balanced viewpoint.
Anyway, within the context of this short attention span wild weasel qualification, take my impressions with a grain of salt. I do know that when Steve and some others have gone to shows we have tended to sync fairly closely in our overall impressions.
There's also the problem that as a long listening day goes on, my listeners get shot, and I am afraid that I am going to get irritable and misjudge things. However, the YG was one of the last ones I heard.
