Auditioning monitors in the store is a crap shoot at best due to the listening environment. Research the reviews of the ones your interested in and then buy the ones that offer the best reviews for the price range your interested in. Save the packaging and receipts and return them if your not completely satisfied and get a different brand.

I do have the KRK Rockit 5's and I like them. Keep in mind that your studio setup (desk, position of your ears and the monitors, sound absorption) will all affect the sound of the monitors. You tube reviews are really bad at determining the sound of the monitors also. You will never get the monitors true sound reproduction through the video or your computer speakers. You are left with the reviewers word on the matter.
