Well by Milhorn and Soix's definition of black, which I understand through their descriptions and have heard in some systems over the years including my first real hi-fi system from the mid 80's with a CJ pre-amp that was really good at this, a darker presentation. It seems to me that such systems are obscuring musical and ambient information with greater focus of the instrument's fundamental tone which would also obscure harmonics, decay and ambient cues of the venue. To me this is clearly less resolving therefore less accurate. Not that it's a bad thing, just a matter of choice, certainly not mine. I have never heard this effect in live music only on hi-fi systems.
So it seems, at least to me, there are different meanings of "the blacks" to different listeners'.
