I'll add my disagreement and say that I think that 5k is a serious chunk of change to spend on a first system. Also, the room is cozy and not huge, which dictates things somewhat.
One other item is that the OP will have preferences in regards to sound that he apparently does not know about yet. So, step one should be the speakers, and with music one is familiar with. Audition the Vandersteens mentioned in post one. Compare them with others to get an idea of what sounds best.
I'm not convinced that the Vandersteens would be the best speaker for the types of music the OP prefers.
