How do the Von Schweikert VR-2's handle loud rock?

I replaced my Krell KRC-3, KSA-50S and Conrad-Johnson D/A-3 over the three last months with a Musical Fidelity A308cr Pre-amp, Amp and Tri-Vista 21 DAC. I have a pair of B&W Silver Signature 25's that I'm using and really, really like. My main musical interest though is rock and keyboard music. The Silver Sigs just don't seem to cut it when trying to approach the level where the emotion really kicks in. I just got laid off due to a bank buyout, so I'm in the position that I have to sell or trade the Silver Sigs and use what I can from that. From everything I've been reading, it sounds like the Von Schweikert VR-4jr's are the way to go. Unfortunately, I don't think I can get the $4000.00 out of my Silver Sigs. The next choice seems to be the VR-2's, but I wondering if they're too small for what I'm looking to do. Another thing, I've never had the chance to listen to the Von Schweikert speakers at all, since the nearest dealer is four hours away. I'd appreciate any thoughts you have on a pair of speakers for under $3500.00 that will work for rock, or if the Silver Sigs will work doing something different. Thanks!
