When we add definition to a signal that we are already familiar with, one of three things can happen:
1) it goes unnoticed - due to poor monitoring, poor hearing or an overactive mind (because we can only hear as well as our minds allow). I got to watch Doug Sax before he passed and the man had a switch in his head that allowed his ear to fall into a sound freakishly deep. Most of us (myself included) aren't born with such a gift so we must develop it at some point in our lives and then maintain it with practice. Doug inspired me in my 20s to develop my own 'switch' which I still use today in my late 40s.
2) it is appreciated - either as improved clarity, improved tonality, improved depth, or improved transient presentation. Something is improved and the ear is pulled further into the music as a result. For me personally, when definition is added, my ear goes straight to the transients that are suddenly presented with added precision, regardless if they were improved or not in amplitude.
3) it is
not appreciated - if your ear is already used to a certain musicality, adding definition can be distracting and therefore unwanted. This has been most apparent for guitar players who are used to a certain cable (between a specific guitar and amp) and then switch to Ghost and the definition is too much. Their ear is now distracted away from the music which is obviously not a good thing. Maybe revisiting the amp settings can bring them back into the tone, or maybe the definition will remain too much, and a duller or slower cable is preferred.
If the left elephant has been your tone all along, suddenly switching to the right elephant might be too much:

Sharpness is to a photo, what articulation is to sound.
IMO there is one place where you want the most definition and that is your monitor path. For better or worse, you've gotta hear what's there in order to do your best work.
And in analog mastering, where the entire mix is dependent on two lines of cable strung between a series of boxes, I want all the definition as I can get no matter how sobering it may be upon playback. This is especially true now as ITB mastering is starting to compete with analog thanks to improved plugin quality as of late. The new Sontec plugin is giving my HW Sontec a run for its money, but I still very much value the sound of my chain and Ghost is playing big role in keeping it competitive with digital. (this is all in my opinion and according to my ear)
