Those who don't like horns are actually not liking what's being sent into them because they are SO sensitive & revealing. Only very refined componentry will make you happy driving horns. Can't help you regarding having "lived with the Avantgarde" but I heard them at a show & liked them (being a horn fan myself). You can drive them with a nice low power SET amp if desired & still get a good slam factor due to the built in bass amps.
