I think musicality means having all the resolution of reference gear but with the smoothness and natural flow of real musicians performing in a space. I am starting to hear this more regularly at RMAF and other shows.
In the past I found numerous systems that had impressive detail but the overall effect was an electronic hash sound that left the impression of the system being artificial.
Musicality preserves the detail but has that "you are there" presence and smoothness.
I don't know if I am making sense here but that's my take on it.
I get it. When audiophiles talk about musicality, I think this is the sort of thing they mean; not just a flat FR. Preserving the things that are important (the core of the music) and giving lower priority to other things, such as pushing the boundaries of the envelope.
When I listen to live acoustic music, I don't hear thundering bass, sparkling highs or scalpel-sharp dynamics or any of the other audiophile watch-words. Real music sounds, well, normal. Because cheap audio gear has a limited envelope, there seems to be a need by manufacturers and buyers to have equipment that works right to the boundaries of the envelope (dynamic range, frequency range etc) and to be very precise and resolving.
This seems to mean that good equipment has to extract every last ounce of detail out of every recording, and if you can produce something that simply sounds
more detailed, then many people see it as better. Now I don't actually like warmth or muddle or softness (I sold my Arcam gear because of that) but it feels like some gear exaggerates detail - not just
more detail, but
too much detail. When I'm in a room with a system that does that, and not really listening, it sounds like its making a hissing, spitting, grtting, screeching, trashy, hashy sound. Its like its trying to thow as much detail at you as possible, regardless of whether its wanted information, or whether it should be there at all. In reality its just noise.
Cheap amplifiers and speakers ( NAD? Bose?) can do it better, as long as they concentrate on getting the core right, and aren't over-ambitious with a huge envelope or huge detail.
Again, I don't think that's necessarily what musicality is all about, but it might be a part of it.
