Next up was the $80k Acapella High Violoncello II—a larger version of the High Violon with an extra woofer inside its box but the same ion tweeter and distinctive horn-loaded midrange. Compared to previous Acapellas, it seemed to have very little horn coloration, although its imaging was a little vague on the Mario Lanza cut, suggesting a slight lack of coherence. On the other hand, it had absolutely no dynamic compression on the punishing Lanza disc, as you might expect from a low-distortion horn speaker, and very high resolution of inner detail. I would have to say that this was the best Acapella speaker I’ve heard. The electronics were from Einstein.
