"Are there speakers out there (new or used) in the $2,500 price range that have the image and soundstage of Magnepan (my current set up is MG12s) but the punch and bass for rock/hip hop type music?"
You might look into bipolar speakers, like the Mirage M1 of yesteryear. Definitive Technology is another possibility. I made bipolars for a while but they were quite a bit more expensive.
