I'm in Gaithersburg, MD, not far from DC and northern Virginia, and Dennis Murphy (owner of Philharmonic Audio and crossover designer for Salk) is nearby in Glen Echo, MD.
Depending on where you are in Virginia, a short day's trip could let you hear several Salk and Philharmonic Audio models. I have Salk Veracity ST speakers, and Dennis always has something different and interesting. His house is a speaker junkie's nirvana. You are welcome to come hear mine, and I know Dennis is usually happy to have visitors interested in speakers.
I realize the Salk Veracity ST speakers I now have are beyond your price range, but they have enough similarities to the Salk SongTower to make them worth hearing.
