If you can budget for HS80m, then I'd go for Adam A5X's, as mentioned by 4andy above. Having said that, I bought the RP6's because my budget was a bit lower; I'm really happy with them, but can also understand why others slate them. They bring a huge smile to my face, but they're perhaps not as accurate as the Yamaha's. But balance is important, many simply seek the flattest or most truthful monitors, which is logical seeing as that's what you're after, but I'd argue within reason you would consider losing a bit of clarity if it meant you got monitors you preferred the sound of slightly more, bearing in mind that you may spend many hours listening to the monitors you buy every day, so you need to like them to a certain degree. I didn't like the Yamaha's as much, hence went KRK.
Also, if you're like me, you've probably deliberated a lot over which to get, understandably so given the prices, but I think people often over-emphasise the differences; I see people saying drastic things like, "love my yammy's, but krk's are impossible to mix on" etc, but once you make your choice, you'll get used to them, and nothing is impossible; there are differences, but they're not huge, not in the price range you're looking at, if you look into it too much, you'll probably take ages to finally decide like I did, and then after it all realise you were probably being a bit OTT.
