Excellent point, Ebonyvette: a very justified mystification, and one that has had me reading b/ween the lines to understand.
Etymologically, an "accurate" speaker will be "musical" or xyz, or whatever the signal fed into it is. Pbb explains this above very well (I would disregard the "subjectivist" & objectivist & other incidental "-ists", however).
As usually used, neither term is "accurate". "Musical", undefined is audiophile mumbo-jumbo: quite appropriately, you defined "musical" above. Most people don't define either term (inlcuding reviewers unfortunately) and use them indiscriminately. Likewise, for "analytical".
What is often meant by "accurate" it seems, is the reproduction of sounds without the energy, dynamic content and/or emotional impact of musicians playing, if you will -- i.e. music that sounds like the musicians are solving a mathematical equation, not putting their soul into the piece...
Or, do I mean "analytical":)?
