Sorry, Jerry. I disagree, although just with the "fall flat on its face" bit
In my view, a really good system ('tuned' to the musical tastes of its owner, if the owner has good ears), and taking the above as an example, should excel with reggae music *or* when presenting a string quartet (whichever its owner prefers), and do justice to the other, i.e. reproduce it with some competence, not fall flat on its face.
If a system falls flat on its face, when reproducing ANY kind of music, then it's not fit for purpose. A really good system should do justice to ALL types of music, albeit excelling with some more than others. I'd expect your system to do that, not fall flat on its face, as indeed does mine.
