Although the subject line of this thread pertains to imaging and soundstaging, I think that the OP and others will find it to be relevant and of interest. My priorities, as listed in that thread in descending order of importance and based on terminology specified by that thread's OP, are:

1. timbreAs others have noted above, these kinds of terms will be defined differently by different audiophiles. That is perhaps especially true in the case of "fullness." But however it may be defined, it seems to me that "body," as referenced by Charles and Robsker, is one of it's essential ingredients, while also being an essential ingredient of timbre, which is no. 1 on my list and the lists of several others in the referenced thread.
2. coherence
3. dynamics
4. bass
5. detail
6. openness
7. imaging
8. air
