I would actually check with Paradigm directly or a local Paradigm dealer, as they manufactuer all their own drivers. You can ususally order original drivers from them through the dealer; I've done it before and a friend has also. For my friend, they actually repaired his Studio 20 for free even though it was out of warranty for a few months (great dealer). Price may not be so friendly though...depends on their inventory if they have them (they should, but no guarantee).
