Monitors aren't boring, it's just because they aren't EQ'ed and made to hide the quality of a recording they are seen that way. The aim with any good speaker is to provide an accurate output of what the original recording sounds like (which is why they use monitors in production so they can critically analyse stuff), which is why trend towards a neutral frequency response. This just means that the bass in a dance song and the bass in country song should be faithful to the recording, where as on cheap speakers that are bass-boosted to sound more 'enjoyable' everything will have a mid-bass hump regardless of whether it was in the original recording or not. Monitors are also designed for nearfield listening, since they sit on/around the mixing desk, where as speakers are generally designed to have some distance between them and the listener.
Obviously different brands will have a slightly different flavour because of parts used, soundstage, sweet spot, frequency roll off at the treble and bass end, fluffy language used to describe how they deliver the sound and so on, but they will all generally share the trait of being neutral enough that people making music will hear what they've actually recorded, rather than a speaker designed to make things like YouTube audio sound less crap than it actually is a lot of the time.
There is a balancing act to be had between how revealing/forgiving you want them to be - because if you listen to a lot of modern music that is recorded/produced/mastered poorly you WILL hear it on good speakers or monitors - but conversely things that are well recorded will sound fantastic, and you may well hear details that you had never picked up before (at least on speakers, since headphones are generally better for microdetail and intimacy with a recording).
I'm looking at the Focal CMS series, but the newer Adam AX series also get good reviews too. The only thing with monitors is some can be fatiguing because of their excellent treble response, such as the Adam A series the AX replaced, but this can all be found out via reviews and looking online.
