shatter, welcome to the forum!
You could always get a receiver by itself to start with, and then decide if you want more power. From what I can tell, there are some quite nice receivers out there for under $2K (Onkyo 875 comes to mind). There are also some nice 200W/channel amps out there for around $2K (Emotiva MPS-1, Outlaw 7700, I'm sure others). That Onkyo, or something equivalent, may make you happy enough that you can save the extra cash. Also, you can always try out a separate amp and return it if you don't like it.
