Vandersteen 3A Sig vs. Von Schweikert VR4 Jr.

I just recently bought a pair of Vand 3's. With some music they sound great. However, for Rock 'N' Roll they appear to be missing something. I was told by the local dealer it was because the Rock 'N' Roll music was recorded. So wondering if the Von VR 4's would be a more rounded speaker to play all types of music. Also, any other other speakers you would recommend in this price range for playing jazz, soft and old Rock 'N' Roll? Thanks for your input.
