JBL S3900

I'm located in the suburban Buffalo,NY area. I'd like to hear from owners of the JBL S3900 speakers who would willing to have me come down for a listening evaluation. I'm willing to travel significant distance to hear them.Also would appreciate comments from those who have actually heard the S3900 compared to the S4700.What are the differences? I've read that the S3900 isn't as smooth as the S4700 in the mids/highs.That's why I need to hear it for myself. I've heard the S4700,and was very impressed with it top to bottom.
