Dark knight's job sounds are amazing. The faint scrape of metal on metal, the faint whispers, all of it really suits the job.

To be honest, though, I play this game silent unless I'm raiding. My computer is in the living room and I don't want to disturb everyone else. Plus, I have incredibly sensitive hearing and a few peculiar issues when exposes to loud sounds for too long, so even when I do have the volume on, it's very low. XIV's strength is that I can play on silent without the sound - the effects are enhancement. The one major exception is Leviathan, where having stereo sound on gives a distinct advantage over visual only. But that's the only real major case.
