Avowed Michael Fremer groupie is very different from saying I really respect his analog reviews.
Okay. And you also said
I read all Fremer articles in detail.
That sounds like a groupie.
But it isn't about him - that's deflection. Mr.Fremer is serving as an example of a knowledgeable person who shares some of microstrip's speaker ownership preferences and publishes commentary about Wilson speakers. You seem to imply that people who review Wison speakers lack knowledge and experience because they do not hear driver 'disparity' or do not write about it and in fact find just the opposite. Perhaps you (absent ownership) do hear that, but that has zero bearing on what others hear and their knowledgeability.
Going from the MAXX 3 ($68,000/pair in 2009) to the much larger, far more costly Alexandria XLF ($210,000/pair) brought with it high expectations, all of which were met. The Alexandria was an improvement in every way—especially on top, where it sounded airier, sweeter, more relaxed, and yet more detailed. Most impressive was that such a tall stack of drivers could produce a 100% coherent, three-dimensional picture from less than 8' away, while managing to sound small or grand, depending on the recording.
Time alignment of the drivers' outputs is not the end-all and be-all of speaker design, but in my experience, once you've grown accustomed to the sort of minimal-baffle, time-aligned driver arrays produced by Wilson and Vandersteen Audio, when you then hear a flat slab speaker, you hear a flat slab, especially in nearfield listening environments like mine.
