Hey guys, I'm looking a nice pair of speakers (2.0) for listening to dance, electronic, and trance music. I'm really after top-notch transient response, detail, and soundstage (I'd go with electrostats, but they're too expensive, too big, and don't quite offer enough bass oomph for my tastes). My budget is to spend less than $400. I'd prefer to buy used to save money. I do not have any preferences for bookshelf vs. floorstanding; whatever sounds the best.
So, any suggestions to look into?
