i'll just add my 2 cents to this conversation, and pardon if someone's already mentioned this and i missed it:
 
if i was a "rule of thumb" kind of guy, which i'm not, i would say spend at least as much on room treatment as on your monitors. if you have a $1k pair of home theater speakers, they could work very well as studio monitors, but not nearly as well as a $500 pair of studio monitors in the same room with $500 worth of proper room treatment. your ears may not lie but your room sure will.
 
most studios can afford several pairs of monitors, of which i imagine the home theater/bookshelf/etc. units are more reference checks vs. actual mixing monitors. i do reference checks on my home theater system (an old sony with 3-foot tower speakers and an infinity sub), my car, my studio headphones, integrated computer and laptop speakers, etc., but i don't mix on any of these (except occasionally the headphones). i found that in my bedroom studio, with 4" bass traps in 2 corners (floor to ceiling) and a fair amount of diffusion, i get much more translatable mixes in far less time than i did in my old space (a medium-sized living room with openings into every other room in the house).
 
the monitors (behringer truths, 8") haven't changed, and i certainly haven't gotten any "better" at mixing. it's simply a far better room setup than i used to have.

Do yourself a favor and before you make up your mind check out the Equator D5s.  They are well within your price range and are superlative.  That said, also check out the Equator D8s which are now shipping.  They are slightly above your price point but are also top tier and large enough to drive the low end you need for orchestral work.

I am surprised you went with the yellow woofers.  What will your clients think?

why would you want clients that hear with their eyes?

I'm saving for mine? You can't go wrong w/Neumann... A Kia will get you across town? A Benz will too... They will both get you across town? One is better than the other. The Kia is fine for most.
 
I have zero complaints about my U87-AI? None... Spitzer could have paid less? But he paid more instead. One could argue he should have paid less? And others could argue that should have paid what he paid, and got his moneys worth.  He could have spent much less, and some would argue he would have gotten the same thing (for much less).  I'm not sure that argument is valid?
 
You can spend much less than did he? And get "something similar?" And in the long run, you may feel better about it? But when you try it for the first time? "You may have buyer's remorse..." Bookshelf or otherwise? I'd rather consider the next notch up personally. I'm not saying the KH120s are Nirvana? They make better speaks :-) JBL makes some nice ones too. My point is, "nothing is free?" Nothing. You can pretend it is? But it's not. i.e., there are cool "secret" guitars? But people seem to gravitate toward the other less secret, more popular ones? There may be a reason for that. (I play a PRS, and I like it, it wasn't cheap in '92 when I got it? But it is sweet to this day...)
 
It is a sweet guitar. And others have many sweet guitars? Some may be a bargain? But I'm betting that "most" are some sort of sweet... Vintage Axe... We all have our weapon of choice? Understand this, the monitors are weapons of choice? Just like your Axe...
 
And don't settle for less than the best that you can afford; whether that be guitars, "companions?", or monitors... And trust me? The money matters "regardless." 

I could never recommend anything by KRK.  They are not neutral and do not translate well.  The Yamahas are very good, especially if you add the subwoofer.  Probably the only un-hyped monitors I have heard in that price range.  The cheaper JBLs are bass heavy and a little muddy by comparison.  I have a $4000 Seas loudspeaker system for my main monitors and I still use my HS50's for consumer reference.  They can pinpoint some things in the mid range that my mains cannot.
