IME, Auditorium-23 Solovox (which I am fortunate to own) and the Shindo Latours (which sadly I will never own). Both are excellent for both singing and speech.
Rather than an indictment of Harbeth, it may be an indictment of playing NPR through your main system. I never do, so can't say. NPR sets the standard for human voice from the radio, but I expect they have it tuned for table radios, car stereo and the like, rather than playback through full-range systems.
dc10audio Berlin has best female vocals I've heard and Leonard Cohen is spooky real.
My guess is paper cone drivers do a much better job than all the ceramic, plastic, and aluminum speaker cones out there I think Vanderseen has a balsa wood pulp cone my guess is that would be fantastic too.
