An interesting question, Onhwy61. I asked a similar one in a thread from a couple years ago. My improvised list of attributes was a little different. It included resolution, soundstaging, PRaT, dynamics, tonal balance, harmonic content, accuracy, coherence, frequency extension, and scale.
From the list you provided, my priorities are...
1. timbre
2. coherence
3. dynamics
4. bass
5. detail
6. openness
7. imaging
8. air
