Well if its vocals to be the key I would go with Axiom Audio. You can get a very nice system for around the $1500 mark, especially if you go through their Factory Outlet. An M22, VP100, QS4s and EP350 sub for slightly more than your budget. I started out with this system and it is one of the cleanest sounding bookshelf systems I have heard. The sub is also pretty good plays almost on par with my SVS PB12-NSD. I know the price is higher than your budget and usually the budget goes out the door once you start looking to upgrade the system anyway. The M22s are wall mountable so no need for stands, just mounts which are a little cheaper. Axiom has a forum of their own and an audition list, check it out to see if anyone lives nearby to give you an audition.

Other than that any of the brands you listed should serve you well. the wait for the X-series just might be worth it, from what I have heard.
