For me, it isn't about the volume, it's about the clarity and accuracy. Live un-amplified sound has a physical characteristic to it. My ideal system would be the one that best replicates this physical presence. Hence I look for dynamics, vocals, piano and strings.
I'm sure it's no surprise, but I much prefer acoustic performances to amplified performances.
