If you want to limit the number of boxes you're playing with, I'd recommend a good integrated amp that combines both amp and preamp. You can get a good used solid state integrated amp, such as a Naim Nait, for under 1K. The advantage of a good solid state unit in this price range would be better bass control than a comparably priced tube unit. On the other hand, you'll get more transparency and natural tonality out of tubes. You need to experiment and see which brings you more satisfaction.
I have to say that I disagree with the comment by Musicnoise. I personally find that I'm more tuned into the nuances of a performance and the emotional communication of artists when I'm listening through a truly high-fidelity system. This is the main reason I'm into the hobby. Sure, I can get into the tweakery of it all, but ultimately, I prefer the musical experience through a high-end system. This doesn't mean than lower fidelity has no place in my life. I have a car system and an iPod and they serve their purpose well.
