I am very familar with only two of these , the Studio 60 and Monitors. However the current model of Monitor is the Silver 6. I have done lots of listening on both these and generally prefer the Monitors for their clean, dynamic sound. Paired with a mellow sounding receiver or amp they are my favorite brand in my area. I like all Paradigm speakers and the Studio series is a great line. Paired with a good receiever, especially NAD or Rotel they are outstanding. The Studio 60 is about $200pr more than the Silver 6 in my area. Either brand is a winner, just make sure you pair them with the right receiver.
