two horn speakers that sounded as good as anyting i've ever heard, were the avantgarde duo's & the jadis eurythmies. and, this was on *any* type of music. outstanding dynamics. everyting was wery detailed & natural, only ting was the soundstage was not as holographic as some conwentional dynamic speakers, or some e-stats. i could be happy w/'em w/som 2a3 set amps, if i could afford 'em, or stand to have 'em sitting in my living room... ;~)
one horn speaker that i haven't heard, but i'd *like* to is the hedlund horn:
