I don't want anyone saying I'm not going to help a brother out!
How about this... I'll be glad to take them off your hands for an even exchange of my Volti Razz. They are a bit taller, not as wide. Finished in a beautiful Walnut with the premium black woven grill cloth. I'll even drive over... kidding of course.
I have no doubt that if you contact Greg at Volti he'll know someone that would buy your pair at a fair price. Then look to Greg to build you a nice pair of Rivals or Razz in any number of amazing finishes..
Personally I like your other option, build a space and keep them. If I could afford either the the original Vittora or the new one about to come out, folks would have to pry them out of my cold dead hands.. 😁
