If you like Electronic type music the Sophia have laser imaging (Merlin's are suppose to have this similar quality) and super fast attack/decay which the VR (basically most conventional speakers) as good as they are can't compete with, this is an electrostatic quality but with more dynamics. With that being said the VR provide more lower mid boom, and you won't need a subwoofer. The VR provide a more fleshed out presentation.
The Sophia is more accurate in the details and control but still sounds similar to a really excellent monitor. The nice thing about the sophia is that it is really tolerant of a wide range of electronics versus WP7's and will work just fine with the JC-1's (but get a warmer preamp or use the audioaero direct). Or even a good integrated (Rowland, Bat,etc)
I have heard VR 4jr's with Naim, I've listened to the Perfectionist system (talk about bass hits!) and my other friend has Sophia's (goten1969) powered by ARC VS55i integrated tube amp resulting in probably one of the most amazing soundstages I've heard. I own WP7's and I have heard the Sophias sound good on VTL, ARC, Rowland and I've heard them sound bad (to hot) on Classe and Levinson.
People either get the Wilson thing or they don't...
