Barry,
I would say you are correct. Though what is 'quality' (using your word) seems to vary a lot more than I would expect.
Recently, did an extended audition with the only change-up being between four pairs of speaker. A friend, and her husband, are looking to get into a higher end audio system and wanted to get a feel for how speakers could be different. Both probably have better ears than me, especially vis a vis live classical music.
Our takes on aspects of the reproduction were very different. Small 'n' but it has played out similarly, with others.
In my experience, for some reason(s), when 'musicality' is discussed folks get easily offended. Therefore, I like Keith's approach, since it forces me to focus on something a bit more specific and somewhat more quantifiable. I imagine, this also makes it easier for the other party to get what I am communicating, since a word like musicality is so indvidually interpreted.
