Verity Parsifals to Von schweikert VR4 Gen III ??

I have the original Verity Audio Parsifal speakers. I'm planning on replacing them with Von Schweikert VR4 Gen III's. My question is this: Do you guys think this is an upgrade or a downgrade? Am I making a mistake?

In appearance and size, the Verity wins. I've never listened to them in the same room nor with the same equipment. I have a Gamut D200 amp so there is no problem driving both speakers. My listening room is 20' X 15' I want to hear from somebody who has experience with these two speakers or opinion.
