If your budget somehow grows to 6k used, the Wilson Sophia are awesome for rock.
With a 3k budget, I really don't think you can do much better than the Gallo 3.1. You can pick these up for around 2k on the 'gon. I am an owner, yes, but I bought them because they pack in so much dynamic punch and sound awesome on rock (and other) music. The replacements (the 3.5) have seemingly minor changes, but will be selling for 6k.
