Von Schweikert VR4SR MK2 any good?


I have a chance to pick a pair of these up! Anybody ever listened to a pair? I currently have Egglstonworks Andra II in my main system and at my cabin I have Aerial Acoustic 10t. Are these an upgrade to the aerials? I’d probably run them in that system as I’m pretty happy with my Andras. Also anybody know what they sold for new and a fair price for a used pair? I’m having trouble putting a value on them.
