Who knows the definitions of "accuracy" and "musicality"?
Do you wish to be imposed by someone's ideas on what the accuracy means? And musicality is your personal matter, what you consider or not musical. Depends also on the music you listen. If you listen to badly recorded heavy metal, for instance, I think there is no issue of musicality, roughly, it should be just loud enough. If you listen to acoustic jazz, then you may compare the sound of your system with that at a live jazz concert. Then I think the musicality and the accuracy should somehow coincide, as you cannot call an inaccurate sound of some instrument musical. Tube amplifies, for instance, normally have much higher harmonic distortion than solid state ones, but I think they are musical and mostly accurate for my ear. I think good speakers must be firstly accurate, and if they reproduce the sound as it was recorded (given that it was recorded well) then you automatically get musicality. Listen to a well recorded human voice / vocal and you will have some idea on how musical and accurate your system sounds.
