An electrostatic loudspeaker is more accurate. In fact the Quad 63 is the only speaekr which can pass a swuare wave. I have heard the orchestra members turning the pages in a 3 dimensional space. However if a rcording was made in a studio not in a "real" space and monitord on dynamic drivers with electronic amplification then dynamic driver will be the best tool to repeoduce that kind of music. I blew up my ESL57s while listening( quite drunk) to a Rolling Stones broadcast concert. Wrong tools for the job.
