Personally I would choose either the Dynaudio BM5a w/matching sub or Adam A7 with matching sub. Street price a little less than $3300 for either of these systems.
Old as in 80's Klipsch KG4's. What I had. Free is a very good price.
I'd like to spend $1000-1500 for 5 identical speakers of the best quality I can get for that much. Passive is preferable as they are multi-purpose as in being my entertainment when I'm working on other things.
The B&W's Geoff suggested were a little out of my price range.
I also use the Blue Sky's and find that I can listen to these for a longer period of time before ear fatigue sets in. I was using the Mackie HR824's before using the Blue Sky's. At least worth a look/listen.
