Not only is it not sheer, but not nonsense at all. Been working in a wine lab for quite a few years, so please, curb your enthusiasm. If a winemaker asks for advice what to do next, we tell him according to what we measure and according to what he wants to make. If not, all we look for is "heads" and "tails" in a wine. If there are none, it's a success. I'd expect your views on wine to be along the lines of "to me" same as in speakers. Which is useless (to the rest).
Let me just focus on these two. They shouldn't be mixed. You're not talking about speakers, but your impressions. The realm of impressions is in one's brain, not inside a box he buys. Given your "brand name dropping", I'd say it's the real audiophile talking. I heard such bad things about Triangles, again, it says nothing about the speakers. (And don't worry, I didn't believe those either).
If you can get "what goes in - comes out" formula for any piece of gear, than "believability" shouldn't come into question.
But you're free to start talking about all the things we can't measure whenever you feel like and save us all some time.
Of course, the fact that you don't like them is as welcome as any other taste, but you're trying to poor it over into a claim about the technical performance of a piece of gear. That's the only part I'm discussing. My guess is that the main reason for this is the fact that you get impressed by exotic. I may be wrong, of course.
