Speakers to consider around 5k used?

I'm a newbie to the high quality world of audio. I'm interested in getting a decent system together. I'm looking for the highest quality speaker in the 4-6k range used. My listening habits are eclectic. Primarily Electronic, Rock/Pop, Classical/Soundtrack, and Traditional/Folk. My room size is an average sized USA house living room. I don't want a speaker that is overly detailed or bright that leads to harshness or fatigue, neither one that is too warm or veiled. I want a neutral speaker that is realistic and true to source without being difficult to listen to, especially in the highs. I am starting with the speakers, and have no other hi-fi equipment. However, I'm considering a network DAC player for my source.

What speakers should I be looking at and which are the best in this range available?

Thanks
