While I have no experience with $3000 or other expensive speaker cables, from a technical standpoint the response by John (Jmcgrogan2), which I know is based on a great deal of experience, makes perfect sense to me.
I would add that given the system and component dependency of cable performance; the technical interactions that are involved between cables and the components they are connecting, which generally don't have a great deal of predictability; and the general lack of quantifiability that seems to characterize cable "science," I wouldn't rule out the possibility that in some cases the $380 cable will provide better results than the $3000 cable.
