I recommend the KEF R100S if you can find a pair. Also you can grab a good used amp and for $1,000 the whole system is upgraded. But it all depends on the music, your ears, and how loud you want it. There is a lot of good gear. I am guessing for $1,000 you can have a nice little setup. We could all list lots of mixes and options, but I prefer one sound and my friend is the opposite. Maybe a nice Klipsch is more your direction.
Best of luck.
