My material is what I'd call light rock and the KRK's just sounded good to me.
So many choices for us to choose from these days.
Just FYI KRK monitors have a huge following among hip-hop engineers/producers, I've been told it's because of the bass translation being accurate. Also very commonly used by rock guys. I like the VXTs because they work for pretty much anything I've thrown at them.
Another very important consideration is ear fatigue. Some speakers seem harder to listen to for hours than others, but of course, that's not something you can evaluate on the floor at GC...nor is it something that shows up in a spec.
Also I've reviewed some speakers that are competitive with KRK (obviously I won't name names) and advertised for studio use, but have a significant bass bump around 100 Hz. That definitely flatters the low end, but if you mix on them, it's a mixed bag because the bass will sound right on something like Beatz headphones but not on more accurate listening systems.
Michael's point about multiple speakers is a very good one, I used to switch among speakers a lot at one point and use headphones as a "reality check." These days, with so many people listening on earbuds and headphones, I switch among headphones (KRK 8400 for overall, AKG 702 for high end, and Beatz for low end, in case you wondered) and use the speakers as a reality check. Times have changed...
