I have VonSchweikert VR4JRs and they sound MUCH better biwired than single wired. I spoke with Albert's son at RMAF and he recommended the biwire option which is about $200. extra. I'd do it if it were me.
As ptmconsulting suggests it does ope up several options for the future; you might want to ask VSA if bi-amping is an option with the bi-wire upgrade.
