von schweikert VR3 vs LSi15

Hello All,
I'm looking at picking up a new pair of speakers to try out. Music:HT = 65:35. I'll be looking into a high current amp soon, possibly an Adcom GFA-555, though I'll be keeping an eye out for a Parasound or B&K, but regardless, any comparisons on these, probably very different, speaker sets? Let me know as I'll be pulling the trigger soon, thanks!!!
