Top two most important sound qualities

In case you didn't know, it's 2023 and this website still hasn't implemented a polling feature, so I can't define a selection of sound qualities to choose from and see results in a grouped, organized fashion. Boo hoo!

If you had to pick two of the typically referenced sound qualities that are most important to you to optimizing the enjoyment of your system, what are they? You know what I mean, right? Could be a certain frequency range and some particular quality that you for in it, or any quality that applies across all frequencies, etc.

(Note: "Sound qualities" mentioned here do not include anything that refers to physical attributes of your system or listening room, such as acoustical treatments, types of components, types of source material, physical tweaks, etc. It's only a reference to subjectively appreciated qualities.)
