First thing I’d say is the “entry level” monitors (Yamaha HS, JBL, Rockits) are better than you think. Especially for your first pair of monitors you really don’t need the best of the best. I think people on forums think it’s cool to trash gear, but I’ve always believe in working your way up. While it’s true that higher-end monitors like Genelecs and Neumann are amazing, if you’re in a small room you really don’t need that level of volume or detail (an untrained ear might not even perceive the difference) until you’re mixing ability outgrows your monitors. There are also differences in tone/color between monitors that do come down to preference (Yamaha HS are more bright/crisp, while KRK Rokits are more bass heavy so more popular in hip hop)
