I think some of the best horns I ever heard were reconstructed "theater" speakers that had their amps wired directly to the voice coils, just as you describe, above.   This was my first notion of the term "dedicated amp", because of this experience.  It may be that the amps in this case were PP, and almost certainly they were 2-stage, although I can't be certain this many years later.  In any case these amp/speakers projected remarkable vitality and immediacy, with very limited resonances for horns of that type, although I have no idea why this would be so, just an observation.
Actually the "theater" speakers were VERY far from the “best horns” and their amps, mostly 3 stages and up, were quite poor as well. I do not share your view that a "dedicated amp" should be coupled to directly to the voice coil. A dedicates concept in SET world is an optimization of circuit and output transformer for the given frequency range and to the given load. Anyhow, the "contemporary" horns are capable to through way more interning and demanding sound then those "theater" speakers… I do not say that voice coils coupling is bad but I say that juts the fact of direct coupling itself if not as the detail that automatically assume anything.
