Describe your preference in a single sentence

Love the responses. It shows the incredible variety when it comes to listening preferences. I can imagine how difficult it must be for audio equipment designers to settle on a specific set of attributes. It is quite obvious you cannot design something that would satisfy everyone equally. If I have to guess, and at the risk of gross oversimplification, designers roughly fall in two overarching categories:

Category 1: Straight wire with a gain. Neutral. Accurate. Excellent 'slam'. Great dynamics. More focus on accuracy while only slightly sacrificing musicality and tonality(?)

Category 2: More focus on tone, timbre, maybe at the expense of dynamics with some coloration(?) Musicality as opposed to ultimate accuracy.

P.S. What do I mean by musicality? See @jjss49 definition please :)

full-frequency neutral clarity combined with mellowness, airy spaciousness with instrumental placement independent of listener position relative to speakers, an utterly undistorted and unfatiguing ease to the presentation that allows for unself-conscious listening for hours and hours to where one loses track of time. 

Sound that moves me…

Loud enough to bother my wife, but good enough for her to take notice.

Enough transparency, detail, resolution, layering, natural timbre, soundstage size and accuracy, depth, bass/mid range richness, separation among other qualities that result in an emotionally engaging listen. 

If the end result is that the music doesn't move you emotionally, it doesn't matter how well your system does one thing or another.
