What music is your system setup for?

I am new here, so hello to everyone.
Did you set your system up for rock, jazz or classical from the get go?
Are your speakers far from the back wall, say 6 feet for a deep sound stage, some say nessesary for classical?
just off the wall, say 3 feet good for rock and some where in between for jazz, or does it matter?
Also what type of music did you purchase your equipment to listen to and is it a compromise when you listen to the other or does that not matter either?
Just thoughtI would ask.
Thanks for your input.
