I have an H120, battery box that I made, CA-11 mics, and CA-9100 pre. If you're recording very loud rock, you honestly won't notice much, if any, difference. If the band is quieter, the H120 will introduce a little noise as you crank the gain and you'll have a cleaner recording with a decent pre. The CA-9100 is quite nice, but if you're poor you can get by fine with a battery box for rock & roll.
