Von Schweikert VR2 verses Infinity RSIIIB

I have been using a friends VR2s and at first thought my Vandersteen 2CEs were better but after much listening I have decided the VR2s are more transparent, more vivid and have more depth and sharper imaging without sounding etched. They are also more holographic. The Vandersteen do something the VRs do not but i can put my finger on it and in the end the VRs are more my cup of tea. I would like to compare them to some older infi9nity RSIIIBs. Is this a waste of time to do this? Am I moving up down or sideways Thanks
