Triode,
Yes, maybe with Avantgarde's I suspect. GOtta hear a pair sometime. I have heard some other very good high efficiency horn based rigs that I am sure can do the job, at least with the right "tweaks". I would expect speakers like those to be quite sensitive to pretty much any change and perhaps more of a challenge to get tuned in properly than others. But once you do, and it stays there, I would expect exceptional results, though perhaps different still from most of what I am used to that sounds good to me with that kind of music in particular.
