all components are imperfect. thus a component cannot be musical, its errors may be pleasant or unpleasant. in all cases there will be inaccuracies of timbre, thus a stereo system and component are not musical.
recordings may approach accuracy of timbre and the sound of a minimally uncolored stereo system, playing a minimally erroneus recording will approach the sound of instruments.
it is a mistake to speak of components as musical. components don't make music, rather instruments do, and recordings are an attempt to recreate the sound of instruments.
it makes sense to discuss components as more or less inaccurate and describe the nature of the inaccuracy.
perhaps, by musicality, you mean euphonically colored.
