I had the JRs and now have the SRs. The SRs are a lot better. I still think the JRs are great speakers, but the SRs just expand on their excellent stregths in all aspects. If you are looking for something totally different and aren't completely happy with the VS sound then good luck, but if you already love the 4JRs and just want to take it to the next level you might be sorry if you stray from the VS line.
