Vandersteen has you ship them UPS in their original boxes, guaranteeing that if they get damaged he will repair them. He then uses a professional shipping firm to return them to you strapped to pallets. You pay the up front UPS, the return shipping is included in your upgrade price.
When I inquired about this, the upgrade came with new socks but NOT new end caps.
The upgrade from 3 to 3Asig costs $1600. Add this to the price for used model 3s (~$900) - be certain to have them shipped from the previous owner directly to Vandersteen.
Upgraded 3Asigs are routinely available on Audiogon for $2800 plus shipping
