Interesting divergences here. Some think that speakers are seeking to get the sound "right" and so there's no reason to have a system B. (Some think I'm asking about replacing their "A" system. That's not the question.)
Others see sound presentation the way many see food -- Italian food one night, Chinese another -- their differences can both deliver excellent dining and one cannot eliminate the other. I'm in this camp. Give me variety in food, music, audio, movies, novels, etc. This is art, not science (for me).
Speaker wise, both Tannoys and Eminent Technology LFT 8's are on my list. Also, Devores.
I'm curious about the punchy "liveness" of horns, the efficiency of concentric drives, the spatialization of planars and ribbons.
