The choice between accuracy and musicality is one that every audiophile faces sooner or later. Although I agree with Jax2 that accuracy and musicality are not NECESSSARILY mutually exclusive, in reality, one is often achieved at the expense of the other. When that happens, we have to choose between them. My impression of the audiophiles on A'gon is that, when cornered, the majority of them would choose musicality over accuracy. Of course, I could be wrong about that.
As Marty pointed out, the choice between accuracy and musicality is an example of the choice between truth and beauty. To some, that may seem an excessively philosophical way of putting it. But that is exactly what is at issue...
Accuracy might be thought of as the objective correspondence of the musical information presented at the ear during playback to the musical information either (1) presented at the microphone during recording, or (2) represented on the software. Either way, accuracy is the correspondence of a representation to reality. And that is what truth is.
Musicality might be thought of as a subjective experience in which musical playback evokes the perceptions and feelings associated with real music. Those perceptions and feelings, while diverse, have an element in common: the pleasure derived from form and content. And that is what beauty is.
So the choice between accuracy and musicality is a version of the choice between truth and beauty. In some contexts, there are moral considerations when choosing between truth and beauty. In a courtroom, for example. But in an audio system, when confronted with the choice between truth and beauty, there is no right or wrong. There is only preference.
Having said that, the changes to my system that I have been the most rewarded by are the ones where accuracy and musicality BOTH improved as a result of the a single change. In other words, when I didnt have to choose between truth and beauty.
