One advantage of having a nice system is listening to it and I think trying new music is an ancillary effect.
I often have Linn Jazz on my system - I have my system on a large portion of the time including when I'm away so my dog doesn't feel alone.
There's some vocal jazz tracks with some amazing vocalists. There was one song I heard - I stopped what I was doing to find out who it was. (It was Nikki Yanofsky) I thought that was really cool!
