"Voices are split in prismatic fashion" is the nail in the coffin, IMO.
From another thread, re Tekton Moab: "Nice, plenty of positive things to say. However, it was quite obvious that the array adds convolution to the imaging, especially with more complex music. Voices are split in prismatic fashion and I could hear the grouping of drivers’ contributing to that….Frankly, for all the tweeters purportedly giving the Moab such incisiveness, not really. The 3" soft dome of [my Wharfdale] Opus 2-M2 to my ears in this system was much more precise and elegant, without the smearing of the multiple drivers’ launch….[Moab] does have a more stringent sound, and does not excel in that system at warmth, even though a relatively recent AR preamp and Pass 30.8 Monos were in use. The bass was ok, but certainly not overwhelming in terms of impact or tonality. For $4K some good scale, acceptable presence and impact; reminded me of a low to mid line Magnepan or Vandersteen, a bargain, but with idiosyncrasies."
