Had a fascinating experience with the Thiel 2.7s last night.
As I’ve mentioned before, they image with a specificity like few other speakers in my experience.
Last night I was listening to the album in which the California Guitar Trio combined forces with the Montreal Guitar Trio for a live performance (album streamed from Tidal). So that is six acoustic (and sometimes electric) guitars lining the stage, close together.
The Thiels imaging was so laser precise that every one of those 6 guitars in a line were easily discernible from the one beside it! They just showed up corporeally in space and I could close my eyes and point directly to each single guitar, even during complex passages. The images of the guitarists were not recorded up front, but are portrayed at a distance. So the instruments are not full sized, but smaller as in further away. This puts the guitars relatively closer to each other in terms of the demands of speaker imaging, and the Thiels literally carved out each guitar in space where I could "see" one end and the other begin only inches away from the other.
For me this is one of the ways good imaging pays dividends - beyond the timbrel cues, he spacial specificity makes it easy to discern what any particular musician is playing in a mix. And the sensation of musicians playing in front of me is more pronounced.
(I’m definitely a "tone and dynamics first" guy, but I also require the speakers to disappear and image well to be fully satisfied spending big bucks on high end audio).
